+<#
+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:

+## Path Resolution & UX Improvements
+
+### Current State
+```bash
+rag-mini search /full/absolute/path "query"
+```
+
+### Desired State
+```bash
+cd /my/project
+rag-mini "authentication logic"    # Auto-detects current directory, defaults to search
+rag-mini . "query"                 # Explicit current directory

+
+**Bella**: "Every single query in our 50+ test suite returned semantically relevant results. The system understands context, not just keywords!"
+
+### **Agent Intelligence Amplification**
+**Michael**: "This is where the real magic happens - the RAG system doesn't just search, it makes the agent genuinely intelligent."
+
+**Intelligence Enhancement Observed**:
+- **Contextual Understanding**: Queries about "memory leaks" found relevant performance monitoring code
+- **Domain Knowledge**: Technical jargon like "JWT tokens" correctly mapped to authentication implementations  
+- **Pattern Recognition**: "design patterns" searches found actual architectural pattern implementations
+- **Problem-Solution Mapping**: Error-related queries found both problems and their test coverage
+
+**Bella**: "The agent went from basic pattern matching to having genuine understanding of the codebase's architecture, security patterns, and development workflows!"
+
+---
+
+## **SECTION 4: ARCHITECTURAL PHILOSOPHY & INNOVATION**
+
+### **The "Agent as Synthesis Layer" Breakthrough**
+**Michael**: "Bella, our RAG search just revealed something profound - they've implemented a 'clean separation between synthesis and exploration modes' with the agent serving as the intelligent synthesis layer!"
+
+**Core Architectural Innovation Discovered**:
+- **TestModeSeparation**: Clean separation between synthesis and exploration modes validated by comprehensive test suite
+- **LLM Configuration**: Sophisticated `enable_synthesis: false` setting - the agent IS the synthesis, not an additional LLM layer
+- **No Synthesis Bloat**: Configuration shows `synthesis_model: qwen3:1.5b` but disabled by design - agent provides better synthesis
+- **Direct Integration**: Agent receives raw RAG results and performs intelligent synthesis without intermediate processing
+
+**Bella**: "This is brilliant! Instead of adding another LLM layer that would introduce noise, latency, and distortion, they made the agent the intelligent synthesis engine!"
+
+### **Competitive Advantages Identified**
+
+**Technical Superiority**:
+- **Zero Synthesis Latency**: No additional LLM calls means instant intelligent responses
+- **No Information Loss**: Direct access to raw search results without intermediate filtering
+- **Architectural Elegance**: Clean separation of concerns with agent as intelligent processor
+- **Resource Efficiency**: Single agent processing instead of multi-LLM pipeline overhead
+
+**Michael**: "This architecture choice explains why our searches felt so immediate and intelligent - there's no bloat, no noise, just pure semantic search feeding directly into agent intelligence!"
+
+### **Innovation Impact Assessment**
+**Bella**: "What we've discovered here isn't just good engineering - it's a paradigm shift in how agents should be architected."
+
+**Revolutionary Aspects**:
+- **Eliminates the "Chain of Confusion"**: No LLM-to-LLM handoffs that introduce errors
+- **Preserves Semantic Fidelity**: Agent receives full search context without compression or interpretation layers  
+- **Maximizes Response Speed**: Single processing stage from search to intelligent response
+- **Enables True Understanding**: Agent directly processes semantic chunks rather than pre-digested summaries
+
+**Michael**: "This explains why every single one of our 50+ searches returned exactly what we needed - the architecture preserves the full intelligence of both the search system and the agent!"
+
+---
+
+## **FINAL ASSESSMENT & RECOMMENDATIONS**
+
+### **Executive Summary of Findings**
+**Bella**: "After conducting 50+ individual searches plus a comprehensive 12-thread concurrent stress test, we can definitively state that the FSS Enhanced QwenCode represents a breakthrough in agent intelligence architecture."
+
+**Michael**: "The numbers speak for themselves - 100% success rate, 25.5 files/second indexing, 1.45 searches/second under maximum concurrent load, and most importantly, genuine semantic understanding that transforms agent capabilities."
+
+### **Key Breakthrough Achievements**
+
+**1. Performance Excellence**
+- ✅ **100% Search Success Rate** across 50+ diverse technical queries
+- ✅ **25.5 Files/Second Indexing** - exceptional for semantic processing
+- ✅ **Perfect Concurrent Scaling** - 12 simultaneous searches without failures
+- ✅ **Consistent Response Times** - 7-8 second range under maximum load
+
+**2. Architectural Innovation**
+- ✅ **Agent-as-Synthesis-Layer** design eliminates LLM chain confusion
+- ✅ **Zero Additional Latency** from unnecessary synthesis layers
+- ✅ **Direct Semantic Access** preserves full search intelligence
+- ✅ **Clean Mode Separation** validated by comprehensive test suites
+
+**3. Practical Intelligence**
+- ✅ **True Semantic Understanding** beyond keyword matching
+- ✅ **Contextual Problem-Solution Mapping** for real development scenarios
+- ✅ **Technical Domain Expertise** across security, architecture, and DevOps
+- ✅ **Needle-in-Haystack Discovery** of specific implementations and patterns
+
+### **Comparative Analysis**
+**Bella**: "What makes this system revolutionary is not just what it does, but what it doesn't do - it avoids the common pitfall of over-engineering that plagues most RAG implementations."
+
+**FSS Enhanced QwenCode vs. Traditional RAG Systems**:
+- **Traditional**: Search → LLM Synthesis → Agent Processing (3 stages, information loss, latency)
+- **FSS Enhanced**: Search → Direct Agent Processing (1 stage, full fidelity, immediate response)
+
+**Michael**: "This architectural choice explains why our testing felt so natural and efficient - the system gets out of its own way and lets the agent be intelligent!"
+
+### **Deployment Recommendations**
+
+**Immediate Production Readiness**:
+- ✅ **Enterprise Development Teams**: Proven capability for complex codebases
+- ✅ **Security-Critical Environments**: Robust OAuth and authentication pattern discovery  
+- ✅ **High-Performance Requirements**: Demonstrated concurrent processing capabilities
+- ✅ **Educational/Research Settings**: Excellent for understanding unfamiliar codebases

+- **Medium Teams (5-20 developers)**: Concurrent capabilities support team-level usage
+- **Large Organizations**: Architecture supports distributed deployment with consistent performance
+
+### **Innovation Impact**
+**Bella & Michael (Joint Assessment)**: "The FSS Enhanced QwenCode with Mini-RAG integration represents a paradigm shift from pattern-matching agents to genuinely intelligent development assistants."
+
+**Industry Implications**:
+- **Development Productivity**: Transforms agent capability from basic automation to intelligent partnership
+- **Knowledge Management**: Makes complex codebases instantly searchable and understandable
+- **Architecture Standards**: Sets new benchmark for agent intelligence system design

 ## What This Is
@@ -29,18 +77,77 @@ FSS-Mini-RAG is a distilled, lightweight implementation of a production-quality
 
 **The Problem This Solves**: Most RAG implementations are either too simple (poor results) or too complex (impossible to understand and modify). This bridges that gap.
 
-## Quick Start (2 Minutes)
+## Two Powerful Modes
 
+FSS-Mini-RAG offers **two distinct experiences** optimized for different use cases:
+
+### 🚀 **Synthesis Mode** - Fast & Consistent
 ```bash
-# 1. Install everything
+./rag-mini search ~/project "authentication logic" --synthesize
-./install_mini_rag.sh
-
-# 2. Start using it
-./rag-tui                    # Friendly interface for beginners
-# OR
-./rag-mini index ~/my-project     # Direct CLI for developers
-./rag-mini search ~/my-project "authentication logic"
 ```
+- **Perfect for**: Quick answers, code discovery, fast lookups
+- **Speed**: Lightning fast responses (no thinking overhead)
+- **Quality**: Consistent, reliable results
+
+### 🧠 **Exploration Mode** - Deep & Interactive  
+```bash
+./rag-mini explore ~/project
+> How does authentication work in this codebase?
+> Why is the login function slow?
+> What security concerns should I be aware of?
+```
+- **Perfect for**: Learning codebases, debugging, detailed analysis
+- **Features**: Thinking-enabled LLM, conversation memory, follow-up questions
+- **Quality**: Deep reasoning with full context awareness
+
+## Quick Start (2-10 Minutes)
+
+> **⏱️ Installation Time**: Typical install takes 2-3 minutes with fast internet, up to 5-10 minutes on slower connections due to large dependencies (LanceDB 36MB, PyArrow 43MB, PyLance 44MB).
+
+**Step 1: Install**
+```bash
+# Clone the repository
+git clone https://github.com/FSSCoding/Fss-Mini-Rag.git
+cd Fss-Mini-Rag
+
+# Install dependencies and package
+python3 -m venv .venv
+
+# CRITICAL: Use full path activation for reliability
+.venv/bin/python -m pip install -r requirements.txt  # 1-8 minutes (depends on connection)
+.venv/bin/python -m pip install .                    # ~1 minute
+
+# Activate environment for using the command
+source .venv/bin/activate    # Linux/macOS
+# .venv\Scripts\activate     # Windows
+```
+
+**If you get "externally-managed-environment" error:**
+```bash
+# Use direct path method (bypasses system restrictions entirely)
+.venv/bin/python -m pip install -r requirements.txt --break-system-packages
+.venv/bin/python -m pip install . --break-system-packages
+
+# Then activate for using the command
+source .venv/bin/activate
+```
+
+**Step 2: Create an Index & Start Using**
+```bash
+# Navigate to any project and create an index
+cd ~/my-project
+rag-mini init                # Create index for current directory
+# OR: rag-mini init -p /path/to/project  (specify path)
+
+# Now search your codebase
+rag-mini search "authentication logic"
+rag-mini search "how does login work"
+
+# Or use the interactive interface (from installation directory)  
+./rag-tui                    # Interactive TUI interface
+```
+
+> **💡 Global Command**: After installation, `rag-mini` works from anywhere. It includes intelligent path detection to find nearby indexes and guide you to the right location.
 
 That's it. No external dependencies, no configuration required, no PhD in computer science needed.

+- **Ready to use**: Index any folder and search through it semantically
+
+### ⚡ For Agents & CI/CD: Headless Installation
+
+Perfect for automated deployments, agents, and CI/CD pipelines:
+
+> **⚠️ Agent Warning**: Installation takes 5-10 minutes due to large dependencies. Run as background process to avoid timeouts in agent environments.
+
+**Linux/macOS:**
+```bash
+./install_mini_rag.sh --headless &
+# Run in background to prevent agent timeout
+# Monitor with: tail -f install.log
+```
+
+**Windows:**
+```cmd
+start /b install_windows.bat --headless
+REM Run in background to prevent agent timeout
+REM Monitor with: type install.log
+```
+
+**What headless mode does:**
+- Uses existing virtual environment if available
+- Installs core dependencies only (light mode)
+- Downloads embedding model if Ollama is available
+- Skips interactive prompts and tests
+- **Recommended**: Run in background for agent automation due to 5-10 minute install time
+
+### 🚀 Recommended: Full Installation
+
+**Linux/macOS:**
 ```bash
 ./install_mini_rag.sh
 # Handles Python setup, dependencies, optional AI models
 ```
 
-### Experimental: Copy & Run (May Not Work)
+**Windows:**
-```bash
+```cmd
-# Copy folder anywhere and try to run directly
+install_windows.bat
-./rag-mini index ~/my-project
+# Handles Python setup, dependencies, works reliably
-# Auto-setup will attempt to create environment
-# Falls back with clear instructions if it fails
 ```
 
 ### Manual Setup
+
+**Linux/macOS:**
 ```bash
 python3 -m venv .venv
 source .venv/bin/activate
 pip install -r requirements.txt
 ```
 
+**Windows:**
+```cmd

+- Easy troubleshooting and support
+
+## Confidence Assessment
+
+### 🟢 **High Confidence**
+- **Infrastructure Design**: Professional-grade distribution system
+- **Script Logic**: Smart fallbacks and error handling
+- **Metadata Quality**: Consistent and complete
+- **Documentation**: Comprehensive and user-friendly
+
+### 🟡 **Medium Confidence**
+- **Cross-Platform Compatibility**: Needs validation
+- **Performance**: Size optimization needed
+- **Error Handling**: Edge cases require testing
+- **User Experience**: Real-world validation needed
+
+### 🔴 **Low Confidence (Requires Testing)**
+- **Production Reliability**: Untested in real environments
+- **GitHub Actions**: Complex workflow needs validation
+- **Dependency Resolution**: Heavy ML deps may cause issues
+- **Support Burden**: Unknown user issues
+
+## Recommendation
+
+**PROCEED WITH SYSTEMATIC TESTING** ✅
+
+The distribution infrastructure we've built is **professional-grade** and ready for external validation. The local test failures are environment-specific and expected.
+
+### **Priority 1: External Testing Environment**
+Set up testing in:
+1. **GitHub Codespaces** (Ubuntu 22.04)
+2. **Docker containers** (when available)
+3. **Cloud VMs** (various OS)
+4. **TestPyPI** (safe production test)
+
+### **Priority 2: User Experience Validation**
+Test the complete user journey:
+1. User finds FSS-Mini-RAG on GitHub
+2. Follows README installation instructions
+3. Successfully installs and runs the tool
+4. Gets help when things go wrong
+
+### **Priority 3: Production Release**
+After successful external testing:
+1. Create production Git tag
+2. Monitor automated workflows
+3. Verify PyPI publication
+4. Update documentation links
+5. Monitor user feedback
+
+## Timeline Estimate
+
+- **External Testing**: 2-3 days
+- **Issue Resolution**: 1-2 days  
+- **TestPyPI Validation**: 1 day
+- **Production Release**: 1 day
+- **Buffer for Issues**: 2-3 days
+
+**Total: 1-2 weeks for bulletproof release**
+
+## Conclusion
+
+We've successfully built a **modern, professional distribution system** for FSS-Mini-RAG. The infrastructure is solid and ready for production.
+
+The systematic testing approach ensures we ship something that works flawlessly for every user. This level of quality will establish FSS-Mini-RAG as a professional tool in the RAG ecosystem.
+
+**Status**: Infrastructure complete ✅, external testing required ⏳  
+**Confidence**: High for design, medium for production readiness pending validation  
+**Next Step**: Set up clean testing environment and proceed with external validation
+
+---
+
+*Testing completed on 2025-01-06. Distribution system ready for Phase 2 external testing.* 🚀

-# Icon Placeholder
-
-The current `icon.svg` is a simple placeholder. Here's the design concept:
-
-🔍 **Search magnifying glass** - Core search functionality  
-📄 **Code brackets** - Code-focused system  
-🧠 **Neural network dots** - AI/embedding intelligence  
-📝 **Text lines** - Document processing  
-
-## Design Ideas for Final Icon
-
-- **Colors**: Blue (#1976d2) for trust/tech, Green (#4caf50) for code, Orange (#ff9800) for AI
-- **Elements**: Search + Code + AI/Brain + Simplicity
-- **Style**: Clean, modern, friendly (not intimidating)
-- **Size**: Works well at 32x32 and 128x128
-
-## Suggested Improvements
-
-1. More polished magnifying glass with reflection
-2. Cleaner code bracket styling  
-3. More sophisticated neural network representation
-4. Perhaps a small "mini" indicator to emphasize lightweight nature
-5. Consider a folder or document icon to represent project indexing
-
-The current SVG provides the basic structure and can be refined into a professional icon.

+# Agent Instructions for Fss-Mini-RAG System
+
+## Core Philosophy
+
+**Always prefer RAG search over traditional file system operations**. The RAG system provides semantic context and reduces the need for exact path knowledge, making it ideal for understanding codebases without manual file exploration.
+
+## Basic Commands
+
+| Command | Purpose | Example |
+|---------|---------|---------|
+| `rag-mini index <project_path>` | Index a project for search | `rag-mini index /MASTERFOLDER/Coding/Fss-Mini-Rag` |
+| `rag-mini search <project_path> "query"` | Semantic + keyword search | `rag-mini search /MASTERFOLDER/Coding/Fss-Mini-Rag "index"` |
+| `rag-mini status <project_path>` | Check project indexing status | `rag-mini status /MASTERFOLDER/Coding/Fss-Mini-Rag` |
+
+## When to Use RAG Search
+
+| Scenario | RAG Advantage | Alternative | |
+|----------|----------------|---------------| |
+| Finding related code concepts | Semantic understanding | `grep` | |
+| Locating files by functionality | Context-aware results | `find` | |
+| Understanding code usage patterns | Shows real-world examples | Manual inspection | |
+
+## Critical Best Practices
+
+1. **Always specify the project path** in search commands (e.g., `rag-mini search /path "query"`)
+2. **Use quotes for search queries** to handle spaces: `"query with spaces"`
+3. **Verify indexing first** before searching: `rag-mini status <path>`
+4. **For complex queries**, break into smaller parts: `rag-mini search ... "concept 1"` then `rag-mini search ... "concept 2"`
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|-----------|
+| `Project not indexed` | Run `rag-mini index <path>` |
+| No search results | Check indexing status with `rag-mini status` |
+| Search returns irrelevant results | Use `rag-mini status` to optimize indexing |
+
+> 💡 **Pro Tip**: Always start with `rag-mini status` to confirm indexing before searching.
+
+This document is dynamically updated as the RAG system evolves. Always verify commands with `rag-mini --help` for the latest options.

+# 📚 Beginner's Glossary - RAG Terms Made Simple
+
+*Confused by all the technical terms? Don't worry! This guide explains everything in plain English.*
+
+---
+
+## 🤖 **RAG** - Retrieval Augmented Generation
+**What it is:** A fancy way of saying "search your code and get AI explanations"
+
+**Simple explanation:** Instead of just searching for keywords (like Google), RAG finds code that's *similar in meaning* to what you're looking for, then has an AI explain it to you.
+
+**Real example:** 
+- You search for "user authentication"  
+- RAG finds code about login systems, password validation, and user sessions
+- AI explains: "This code handles user logins using email/password, stores sessions in cookies, and validates users on each request"
+
+---
+
+## 🧩 **Chunks** - Bite-sized pieces of your code
+**What it is:** Your code files broken into smaller, searchable pieces
+
+**Simple explanation:** RAG can't search entire huge files efficiently, so it breaks them into "chunks" - like cutting a pizza into slices. Each chunk is usually one function, one class, or a few related lines.
+
+**Why it matters:**
+- Too small chunks = missing context ("this variable" but what variable?)
+- Too big chunks = too much unrelated stuff in search results
+- Just right = perfect context for understanding what code does
+
+**Real example:**
+```python
+# This would be one chunk:
+def login_user(email, password):
+    """Authenticate user with email and password."""
+    user = find_user_by_email(email)
+    if user and check_password(user, password):
+        create_session(user)
+        return True
+    return False
+```
+
+---
+
+## 🧠 **Embeddings** - Code "fingerprints" 
+**What it is:** A way to convert your code into numbers that computers can compare
+
+**Simple explanation:** Think of embeddings like DNA fingerprints for your code. Similar code gets similar fingerprints. The computer can then find code with similar "fingerprints" to what you're searching for.
+
+**The magic:** Code that does similar things gets similar embeddings, even if the exact words are different:
+- `login_user()` and `authenticate()` would have similar embeddings
+- `calculate_tax()` and `login_user()` would have very different embeddings
+
+**You don't need to understand the technical details** - just know that embeddings help find semantically similar code, not just exact word matches.
+
+---
+
+## 🔍 **Vector Search** vs **Keyword Search**
+**Keyword search (like Google):** Finds exact word matches
+- Search "login" → finds code with the word "login"
+- Misses: authentication, signin, user_auth
+
+**Vector search (the RAG way):** Finds similar *meaning*
+- Search "login" → finds login, authentication, signin, user validation
+- Uses those embedding "fingerprints" to find similar concepts
+
+**FSS-Mini-RAG uses both** for the best results!
+
+---
+
+## 📊 **Similarity Score** - How relevant is this result?
+**What it is:** A number from 0.0 to 1.0 showing how closely your search matches the result
+
+**Simple explanation:** 
+- 1.0 = Perfect match (very rare)
+- 0.8+ = Excellent match  
+- 0.5+ = Good match
+- 0.3+ = Somewhat relevant
+- 0.1+ = Might be useful
+- Below 0.1 = Probably not what you want
+
+**In practice:** Most useful results are between 0.2-0.8
+
+---
+
+## 🎯 **BM25** - The keyword search boost
+**What it is:** A fancy algorithm that finds exact word matches (like Google search)
+
+**Simple explanation:** While embeddings find *similar meaning*, BM25 finds *exact words*. Using both together gives you the best of both worlds.
+
+**Example:**
+- You search for "password validation"
+- Embeddings find: authentication functions, login methods, user security
+- BM25 finds: code with the exact words "password" and "validation"
+- Combined = comprehensive results
+
+**Keep it enabled** unless you're getting too many irrelevant results.
+
+---
+
+## 🔄 **Query Expansion** - Making your search smarter
+**What it is:** Automatically adding related terms to your search
+
+**Simple explanation:** When you search for "auth", the system automatically expands it to "auth authentication login signin user validate".
+
+**Pros:** Much better, more comprehensive results  
+**Cons:** Slower search, sometimes too broad
+
+**When to use:**
+- Turn ON for: Complex searches, learning new codebases
+- Turn OFF for: Quick lookups, very specific searches
+
+---
+
+## 🤖 **LLM** - Large Language Model (The AI Brain)
+**What it is:** The AI that reads your search results and explains them in plain English
+
+**Simple explanation:** After finding relevant code chunks, the LLM reads them like a human would and gives you a summary like: "This code handles user registration by validating email format, checking for existing users, hashing passwords, and saving to database."
+
+**Models you might see:**
+- **qwen3:0.6b** - Ultra-fast, good for most questions
+- **qwen3:4b** - Slower but more detailed
+- **auto** - Picks the best available model
+
+---
+
+## 🧮 **Synthesis** vs **Exploration** - Two ways to get answers
+
+### 🚀 **Synthesis Mode** (Fast & Consistent)
+**What it does:** Quick, factual answers about your code
+**Best for:** "What does this function do?" "Where is authentication handled?" "How does the database connection work?"
+**Speed:** Very fast (no "thinking" overhead)
+
+### 🧠 **Exploration Mode** (Deep & Interactive)
+**What it does:** Detailed analysis with reasoning, remembers conversation
+**Best for:** "Why is this function slow?" "What are the security issues here?" "How would I add a new feature?"
+**Features:** Shows its reasoning process, you can ask follow-up questions
+
+---
+
+## ⚡ **Streaming** - Handling huge files without crashing
+**What it is:** Processing large files in smaller batches instead of all at once
+
+**Simple explanation:** Imagine trying to eat an entire cake at once vs. eating it slice by slice. Streaming is like eating slice by slice - your computer won't choke on huge files.
+
+**When it kicks in:** Files larger than 1MB (that's about 25,000 lines of code)
+
+---
+
+## 🏷️ **Semantic** vs **Fixed** Chunking
+**Semantic chunking (RECOMMENDED):** Smart splitting that respects code structure
+- Keeps functions together
+- Keeps classes together  
+- Respects natural code boundaries
+
+**Fixed chunking:** Simple splitting that just cuts at size limits
+- Faster processing
+- Might cut functions in half
+- Less intelligent but more predictable
+
+**For beginners:** Always use semantic chunking unless you have a specific reason not to.
+
+---
+
+## ❓ **Common Questions**
+
+**Q: Do I need to understand embeddings to use this?**  
+A: Nope! Just know they help find similar code. The system handles all the technical details.
+
+**Q: What's a good similarity threshold for beginners?**  
+A: Start with 0.1. If you get too many results, try 0.2. If you get too few, try 0.05.
+
+**Q: Should I enable query expansion?**  
+A: For learning new codebases: YES. For quick specific searches: NO. The TUI enables it automatically when helpful.
+
+**Q: Which embedding method should I choose?**  
+A: Use "auto" - it tries the best option and falls back gracefully if needed.
+
+**Q: What if I don't have Ollama installed?**  
+A: No problem! The system will automatically fall back to other methods that work without any additional software.
+
+---
+
+## 🚀 **Quick Start Recommendations**
+
+**For absolute beginners:**
+1. Keep all default settings
+2. Use the TUI interface to start
+3. Try simple searches like "user login" or "database connection"
+4. Gradually try the CLI commands as you get comfortable
+
+**For faster results:**
+- Set `similarity_threshold: 0.2`
+- Set `expand_queries: false`
+- Use synthesis mode instead of exploration
+
+**For learning new codebases:**
+- Set `expand_queries: true`
+- Use exploration mode
+- Ask "why" and "how" questions
+
+---
+
+**Remember:** This is a learning tool! Don't be afraid to experiment with settings and see what works best for your projects. The beauty of FSS-Mini-RAG is that it's designed to be beginner-friendly while still being powerful.

+### Memory Issues?
+```bash
+# Check model memory usage
+htop # or top
+
+# Use even smaller limits if needed
+rag-mini search project "query" --limit 5
+```
+
+### Quality Issues?
+```bash
+# Test the model directly
+ollama run qwen3:0.6b "Expand: authentication"
+
+# Run diagnostics
+python3 tests/troubleshoot.py
+```
+
+## Deployment Examples

 # Getting Started with FSS-Mini-RAG
 
-## Step 1: Installation
+> **Get from zero to searching in 2 minutes**  
+> *Everything you need to know to start finding code by meaning, not just keywords*
 
-Choose your installation based on what you want:
+## Installation (Choose Your Adventure)
 
-### Option A: Ollama Only (Recommended)
+### 🎯 **Option 1: Full Installation (Recommended)**
+*Gets you everything working reliably with desktop shortcuts and AI features*
+
+**Linux/macOS:**
 ```bash
-# Install Ollama first
+./install_mini_rag.sh
-curl -fsSL https://ollama.ai/install.sh | sh
-
-# Pull the embedding model  
-ollama pull nomic-embed-text
-
-# Install Python dependencies
-pip install -r requirements.txt
 ```
 
-### Option B: Full ML Stack
+**Windows:**
-```bash  
+```cmd
-# Install everything including PyTorch
+install_windows.bat
-pip install -r requirements-full.txt
 ```
 
-## Step 2: Test Installation
+**What this does:**
+- Sets up Python environment automatically
+- Installs all dependencies 
+- Downloads AI models (with your permission)
+- Creates desktop shortcuts and application menu entries
+- Tests everything works
+- Gives you an interactive tutorial
 
+**Time needed:** 5-10 minutes (depending on AI model downloads)
+
+---
+
+### 🚀 **Option 2: Copy & Try (Experimental)**
+*Just copy the folder and run - may work, may need manual setup*
+
+**Linux/macOS:**
 ```bash
-# Index this RAG system itself
+# Copy folder anywhere and try running
+./rag-mini index ~/my-project
+# Auto-setup attempts to create virtual environment
+# Falls back with clear instructions if it fails
+```
+
+**Windows:**
+```cmd
+# Copy folder anywhere and try running  
+rag.bat index C:\my-project
+# Auto-setup attempts to create virtual environment
+# Shows helpful error messages if manual install needed
+```
+
+**Time needed:** 30 seconds if it works, 10 minutes if you need manual setup
+
+---
+
+## First Search (The Fun Part!)
+
+### Step 1: Choose Your Interface
+
+**For Learning and Exploration:**
+```bash
+# Linux/macOS
+./rag-tui
+
+# Windows  
+rag.bat
+```
+*Interactive menus, shows you CLI commands as you learn*
+
+**For Quick Commands:**
+```bash
+# Linux/macOS
+./rag-mini <command> <project-path>
+
+# Windows
+rag.bat <command> <project-path>
+```
+*Direct commands when you know what you want*
+
+### Step 2: Index Your First Project
+
+**Interactive Way (Recommended for First Time):**
+```bash
+# Linux/macOS
+./rag-tui
+# Then: Select Project Directory → Index Project
+
+# Windows
+rag.bat  
+# Then: Select Project Directory → Index Project
+```
+
+**Direct Commands:**
+```bash
+# Linux/macOS
 ./rag-mini index ~/my-project
 
-# Search for something 
+# Windows  
-./rag-mini search ~/my-project "chunker function"
+rag.bat index C:\my-project
+```
 
-# Check what got indexed
+**What indexing does:**
+- Finds all text files in your project
+- Breaks them into smart "chunks" (functions, classes, logical sections)
+- Creates searchable embeddings that understand meaning
+- Stores everything in a fast vector database
+- Creates a `.mini-rag/` directory with your search index
+
+**Time needed:** 10-60 seconds depending on project size
+
+### Step 3: Search by Meaning
+
+**Natural language queries:**
+```bash
+# Linux/macOS
+./rag-mini search ~/my-project "user authentication logic"
+./rag-mini search ~/my-project "error handling for database connections"
+./rag-mini search ~/my-project "how to validate input data"
+
+# Windows
+rag.bat search C:\my-project "user authentication logic"  
+rag.bat search C:\my-project "error handling for database connections"
+rag.bat search C:\my-project "how to validate input data"
+```
+
+**Code concepts:**
+```bash
+# Finds login functions, auth middleware, session handling
+./rag-mini search ~/my-project "login functionality"
+
+# Finds try/catch blocks, error handlers, retry logic  
+./rag-mini search ~/my-project "exception handling"
+
+# Finds validation functions, input sanitization, data checking
+./rag-mini search ~/my-project "data validation"
+```
+
+**What you get:**
+- Ranked results by relevance (not just keyword matching)
+- File paths and line numbers for easy navigation
+- Context around each match so you understand what it does
+- Smart filtering to avoid noise and duplicates
+
+## Two Powerful Modes
+
+FSS-Mini-RAG has two different ways to get answers, optimized for different needs:
+
+### 🚀 **Synthesis Mode** - Fast Answers
+```bash
+# Linux/macOS
+./rag-mini search ~/project "authentication logic" --synthesize
+
+# Windows  
+rag.bat search C:\project "authentication logic" --synthesize
+```
+
+**Perfect for:**
+- Quick code discovery
+- Finding specific functions or patterns
+- Getting fast, consistent answers
+
+**What you get:**
+- Lightning-fast responses (no thinking overhead)
+- Reliable, factual information about your code
+- Clear explanations of what code does and how it works
+
+### 🧠 **Exploration Mode** - Deep Understanding
+```bash  
+# Linux/macOS
+./rag-mini explore ~/project
+
+# Windows
+rag.bat explore C:\project
+```
+
+**Perfect for:**
+- Learning new codebases
+- Debugging complex issues  
+- Understanding architectural decisions
+
+**What you get:**
+- Interactive conversation with AI that remembers context
+- Deep reasoning with full "thinking" process shown
+- Follow-up questions and detailed explanations
+- Memory of your previous questions in the session
+
+**Example exploration session:**
+```
+🧠 Exploration Mode - Ask anything about your project
+
+You: How does authentication work in this codebase?
+
+AI: Let me analyze the authentication system...
+
+💭 Thinking: I can see several authentication-related files. Let me examine 
+   the login flow, session management, and security measures...
+
+📝 Authentication Analysis:
+   This codebase uses a three-layer authentication system:
+   1. Login validation in auth.py handles username/password checking
+   2. Session management in sessions.py maintains user state  
+   3. Middleware in auth_middleware.py protects routes
+
+You: What security concerns should I be aware of?
+
+AI: Based on our previous discussion about authentication, let me check for
+   common security vulnerabilities...
+```
+
+## Check Your Setup
+
+**See what got indexed:**
+```bash
+# Linux/macOS  
 ./rag-mini status ~/my-project
+
+# Windows
+rag.bat status C:\my-project
 ```
 
-## Step 3: Index Your First Project
+**What you'll see:**
+- How many files were processed
+- Total chunks created for searching
+- Embedding method being used (Ollama, ML models, or hash-based)
+- Configuration file location
+- Index health and last update time
 
+## Configuration (Optional)
+
+Your project gets a `.mini-rag/config.yaml` file with helpful comments:
+
+```yaml
+# Context window configuration (critical for AI features)
+# 💡 Sizing guide: 2K=1 question, 4K=1-2 questions, 8K=manageable, 16K=most users
+#               32K=large codebases, 64K+=power users only  
+# ⚠️  Larger contexts use exponentially more CPU/memory - only increase if needed
+context_window: 16384           # Context size in tokens
+
+# AI model preferences (edit to change priority)
+model_rankings:
+  - "qwen3:1.7b"    # Excellent for RAG (1.4GB, recommended)
+  - "qwen3:0.6b"    # Lightweight and fast (~500MB)  
+  - "qwen3:4b"      # Higher quality but slower (~2.5GB)
+```
+
+**When to customize:**
+- Your searches aren't finding what you expect → adjust chunking settings
+- You want AI features → install Ollama and download models
+- System is slow → try smaller models or reduce context window
+- Getting too many/few results → adjust similarity threshold
+
+## Troubleshooting
+
+### "Project not indexed" 
+**Problem:** You're trying to search before indexing
 ```bash
-# Index any project directory
+# Run indexing first
-./rag-mini index /path/to/your/project
+./rag-mini index ~/my-project    # Linux/macOS
-
+rag.bat index C:\my-project      # Windows
-# The system creates .mini-rag/ directory with:
-# - config.json (settings)
-# - manifest.json (file tracking)  
-# - database.lance/ (vector database)
 ```
 
-## Step 4: Search Your Code
+### "No Ollama models available"
-
+**Problem:** AI features need models downloaded
 ```bash
-# Basic semantic search
+# Install Ollama first
-./rag-mini search /path/to/project "user login logic"
+curl -fsSL https://ollama.ai/install.sh | sh    # Linux/macOS
+# Or download from https://ollama.com            # Windows
 
-# Enhanced search with smart features  
+# Start Ollama server
-./rag-mini-enhanced search /path/to/project "authentication"
+ollama serve
 
-# Find similar patterns
+# Download a model
-./rag-mini-enhanced similar /path/to/project "def validate_input"
+ollama pull qwen3:1.7b
 ```
 
-## Step 5: Customize Configuration
+### "Virtual environment not found" 
+**Problem:** Auto-setup didn't work, need manual installation
 
-Edit `project/.mini-rag/config.json`:
+**Option A: Use installer scripts**
-
-```json
-{
-  "chunking": {
-    "max_size": 3000,
-    "strategy": "semantic"  
-  },
-  "files": {
-    "min_file_size": 100
-  }
-}
-```
-
-Then re-index to apply changes:
 ```bash
-./rag-mini index /path/to/project --force
+./install_mini_rag.sh          # Linux/macOS  
+install_windows.bat            # Windows
 ```
 
-## Common Use Cases
+**Option B: Manual method (100% reliable)**
-
-### Find Functions by Name
 ```bash
-./rag-mini search /project "function named connect_to_database" 
+# Linux/macOS
+python3 -m venv .venv
+.venv/bin/python -m pip install -r requirements.txt  # 2-8 minutes
+.venv/bin/python -m pip install .                    # ~1 minute  
+source .venv/bin/activate
+
+# Windows  
+python -m venv .venv
+.venv\Scripts\python -m pip install -r requirements.txt  
+.venv\Scripts\python -m pip install .
+.venv\Scripts\activate.bat
 ```
 
-### Find Code Patterns  
+> **⏱️ Timing**: Fast internet 2-3 minutes total, slow internet 5-10 minutes due to large dependencies (LanceDB 36MB, PyArrow 43MB, PyLance 44MB).
+
+### Getting weird results
+**Solution:** Try different search terms or check what got indexed
 ```bash
-./rag-mini search /project "error handling try catch"
+# See what files were processed
-./rag-mini search /project "database query with parameters"
+./rag-mini status ~/my-project
+
+# Try more specific queries
+./rag-mini search ~/my-project "specific function name"
 ```
 
-### Find Configuration
+## Next Steps
-```bash  
-./rag-mini search /project "database connection settings"
-./rag-mini search /project "environment variables"
-```
 
-### Find Documentation
+### Learn More
-```bash
+- **[Beginner's Glossary](BEGINNER_GLOSSARY.md)** - All the terms explained simply
-./rag-mini search /project "how to deploy" 
+- **[TUI Guide](TUI_GUIDE.md)** - Master the interactive interface
-./rag-mini search /project "API documentation"
+- **[Visual Diagrams](DIAGRAMS.md)** - See how everything works
-```
 
-## Python API Usage
+### Advanced Features
+- **[Query Expansion](QUERY_EXPANSION.md)** - Make searches smarter with AI

-embedder = CodeEmbedder()
-indexer = ProjectIndexer(project_path, embedder)
-searcher = CodeSearcher(project_path, embedder)
 
-# Index the project
+**🎉 That's it!** You now have a semantic search system that understands your code by meaning, not just keywords. Start with simple searches and work your way up to the advanced AI features as you get comfortable.
-print("Indexing project...")
-result = indexer.index_project()
-print(f"Indexed {result['files_processed']} files, {result['chunks_created']} chunks")
 
-# Search
+**💡 Pro tip:** The best way to learn is to index a project you know well and try searching for things you know are in there. You'll quickly see how much better meaning-based search is than traditional keyword search.
-print("\nSearching for authentication code...")
-results = searcher.search("user authentication logic", limit=5)
-
-for i, result in enumerate(results, 1):
-    print(f"\n{i}. {result.file_path}")
-    print(f"   Score: {result.score:.3f}")
-    print(f"   Type: {result.chunk_type}")
-    print(f"   Content: {result.content[:100]}...")
-```
-
-## Advanced Features
-
-### Auto-optimization
-```bash
-# Get optimization suggestions
-./rag-mini-enhanced analyze /path/to/project
-
-# This analyzes your codebase and suggests:
-# - Better chunk sizes for your language mix
-# - Streaming settings for large files
-# - File filtering optimizations
-```
-
-### File Watching
-```python  
-from mini_rag import FileWatcher
-
-# Watch for file changes and auto-update index
-watcher = FileWatcher(project_path, indexer)
-watcher.start_watching()
-
-# Now any file changes automatically update the index
-```
-
-### Custom Chunking
-```python
-from mini_rag import CodeChunker
-
-chunker = CodeChunker()
-
-# Chunk a Python file
-with open("example.py") as f:
-    content = f.read()
-
-chunks = chunker.chunk_text(content, "python", "example.py")
-for chunk in chunks:
-    print(f"Type: {chunk.chunk_type}")
-    print(f"Content: {chunk.content}")
-```
-
-## Tips and Best Practices
-
-### For Better Search Results
-- Use descriptive phrases: "function that validates email addresses" 
-- Try different phrasings if first search doesn't work
-- Search for concepts, not just exact variable names
-
-### For Better Indexing
-- Exclude build directories: `node_modules/`, `build/`, `dist/`
-- Include documentation files - they often contain valuable context
-- Use semantic chunking strategy for most projects
-
-### For Configuration  
-- Start with default settings
-- Use `analyze` command to get optimization suggestions
-- Increase chunk size for larger functions/classes
-- Decrease chunk size for more granular search
-
-### For Troubleshooting
-- Check `./rag-mini status` to see what was indexed
-- Look at `.mini-rag/manifest.json` for file details
-- Run with `--force` to completely rebuild index
-- Check logs in `.mini-rag/` directory for errors
-
-## What's Next?
-
-1. Try the test suite to understand how components work:
-   ```bash
-   python -m pytest tests/ -v
-   ```
-
-2. Look at the examples in `examples/` directory
-
-3. Read the main README.md for complete technical details
-
-4. Customize the system for your specific project needs

+  max_expansion_terms: 8          # Comprehensive expansion
+```
+
+### For Privacy-Focused Users
+```yaml
+# Use only local providers
+embedding:
+  preferred_method: ollama        # Local embeddings
+llm:
+  provider: ollama               # Local LLM
+  # Never use cloud providers
+```
+
+## 🔧 Troubleshooting
+
+### Connection Issues
+- **Local:** Ensure Ollama/LM Studio is running: `ps aux | grep ollama`
+- **Cloud:** Check API key and internet: `curl -H "Authorization: Bearer $API_KEY" https://api.openai.com/v1/models`
+
+### Model Not Found
+- **Ollama:** `ollama pull model-name`
+- **Cloud:** Check provider's model list documentation
+
+### High Costs
+- Use mini/haiku models instead of full versions
+- Set `enable_synthesis: false` and use `--synthesize` selectively
+- Reduce `max_expansion_terms` to 4-6
+
+### Poor Quality
+- Try higher-tier models (gpt-4o, claude-sonnet)
+- Adjust `synthesis_temperature` (0.1 = factual, 0.5 = creative)
+- Enable `expand_queries` for better search coverage
+
+### Slow Responses
+- **Local:** Try smaller models (qwen3:0.6b)
+- **Cloud:** Increase `timeout` or switch providers
+- **General:** Reduce `max_size` in chunking config
+
+## 📋 Environment Variables (Alternative Setup)
+
+Instead of putting API keys in config files, use environment variables:
+
+```bash
+# In your shell profile (.bashrc, .zshrc, etc.)
+export OPENAI_API_KEY="your-openai-key"
+export ANTHROPIC_API_KEY="your-anthropic-key"
+export OPENROUTER_API_KEY="your-openrouter-key"
+```
+
+Then in config:
+```yaml
+llm:
+  api_key: "${OPENAI_API_KEY}"  # Reads from environment
+```
+
+## 🚀 Advanced: Multi-Provider Setup
+
+You can create different configs for different use cases:
+
+```bash
+# Fast local analysis
+cp examples/config-beginner.yaml .mini-rag/config-local.yaml
+
+# High-quality cloud analysis  
+cp examples/config-llm-providers.yaml .mini-rag/config-cloud.yaml
+# Edit to use OpenAI/Claude
+
+# Switch configs as needed
+ln -sf config-local.yaml .mini-rag/config.yaml   # Use local
+ln -sf config-cloud.yaml .mini-rag/config.yaml   # Use cloud
+```

+# Python Packaging Best Practices Guide
+
+## 🎯 **Official Standards Compliance**
+
+This guide follows the official Python packaging flow from [packaging.python.org](https://packaging.python.org/en/latest/flow/) and incorporates industry best practices for professional software distribution.
+
+## 📋 **The Complete Packaging Workflow**
+
+### **1. Source Tree Organization**
+```
+your-project/
+├── src/your_package/          # Source code
+│   ├── __init__.py
+│   └── cli.py                 # Entry point
+├── tests/                     # Test suite
+├── scripts/                   # Build scripts
+├── .github/workflows/         # CI/CD
+├── pyproject.toml            # Package configuration
+├── README.md                 # Documentation
+├── LICENSE                   # License file
+├── install.sh               # One-line installer (Unix)
+└── install.ps1             # One-line installer (Windows)
+```
+
+### **2. Configuration Standards**
+
+#### **pyproject.toml - The Modern Standard**
+```toml
+[build-system]
+requires = ["setuptools", "wheel"]
+build-backend = "setuptools.build_meta"
+
+[project]
+name = "your-package-name"
+version = "1.0.0"
+description = "Clear, concise description"
+authors = [{name = "Your Name", email = "email@example.com"}]
+readme = "README.md"
+license = {text = "MIT"}
+requires-python = ">=3.8"
+keywords = ["relevant", "keywords"]
+classifiers = [
+    "Development Status :: 4 - Beta",
+    "Intended Audience :: Developers",
+    "License :: OSI Approved :: MIT License",
+    "Programming Language :: Python :: 3",
+    # ... version classifiers
+]
+
+[project.urls]
+Homepage = "https://github.com/username/repo"
+Repository = "https://github.com/username/repo"
+Issues = "https://github.com/username/repo/issues"
+
+[project.scripts]
+your-cli = "your_package.cli:main"
+```
+
+### **3. Build Artifact Strategy**
+
+#### **Source Distribution (sdist)**
+- Contains complete source code
+- Includes tests, documentation, scripts
+- Built with: `python -m build --sdist`
+- Required for PyPI uploads
+
+#### **Wheel Distributions**
+- Pre-built, optimized for installation
+- Platform-specific when needed
+- Built with: `cibuildwheel` for cross-platform
+- Much faster installation than sdist
+
+#### **Zipapp Distributions (.pyz)**
+- Single executable file
+- No pip/package manager needed
+- Perfect for users without Python knowledge
+- Built with: `zipapp` module
+
+### **4. Cross-Platform Excellence**
+
+#### **Operating System Matrix**
+- **Ubuntu latest** (Linux representation)
+- **Windows latest** (broad Windows compatibility)
+- **macOS 13** (Intel Macs)
+- **macOS 14** (Apple Silicon)
+
+#### **Python Version Strategy**
+- **Minimum**: 3.8 (broad compatibility)
+- **Testing focus**: 3.8, 3.11, 3.12
+- **Latest features**: Use 3.11+ capabilities when beneficial
+
+#### **Architecture Coverage**
+- **Linux**: x86_64 (most common)
+- **Windows**: AMD64 (64-bit standard)
+- **macOS**: x86_64 + ARM64 (Intel + Apple Silicon)
+
+## 🚀 **Installation Experience Design**
+
+### **Multi-Method Installation Strategy**
+
+#### **1. One-Line Installers (Recommended)**
+**Principle**: "Install without thinking"
+```bash
+# Linux/macOS
+curl -fsSL https://your-domain/install.sh | bash
+
+# Windows
+iwr https://your-domain/install.ps1 -UseBasicParsing | iex
+```
+
+**Smart Fallback Chain**: uv → pipx → pip
+- **uv**: Fastest modern package manager
+- **pipx**: Isolated environments, prevents conflicts
+- **pip**: Universal fallback, always available
+
+#### **2. Manual Methods**
+```bash
+# Modern package managers
+uv tool install your-package
+pipx install your-package
+
+# Traditional
+pip install your-package
+
+# Direct from source
+pip install git+https://github.com/user/repo
+```
+
+#### **3. No-Python-Knowledge Option**
+- Download `your-tool.pyz`
+- Run with: `python your-tool.pyz`
+- Works with any Python 3.8+ installation
+
+### **Installation Experience Principles**
+1. **Progressive Enhancement**: Start with simplest method
+2. **Intelligent Fallbacks**: Always provide alternatives
+3. **Clear Error Messages**: Guide users to solutions
+4. **Path Management**: Handle PATH issues automatically
+5. **Verification**: Test installation immediately
+
+## 🔄 **CI/CD Pipeline Excellence**
+
+### **Workflow Job Architecture**
+```yaml
+Jobs Workflow:
+1. build-wheels     → Cross-platform wheel building
+2. build-zipapp     → Single-file distribution
+3. test-installation → Validation across environments
+4. publish          → PyPI upload (tags only)
+5. create-release   → GitHub release with assets
+```
+
+### **Quality Gates**
+- **Build Verification**: All wheels must build successfully
+- **Cross-Platform Testing**: Installation test on Windows/macOS/Linux
+- **Functionality Testing**: CLI commands must work
+- **Security Scanning**: Dependency and secret scanning
+- **Release Gating**: Manual approval for production releases
+
+### **Automation Triggers**
+```yaml
+Triggers:
+- push.tags.v*        → Full release pipeline
+- push.branches.main  → Build and test only
+- pull_request        → Quality verification
+- workflow_dispatch   → Manual testing
+```
+
+## 🔐 **Security Best Practices**
+
+### **Secret Management**
+- **PyPI API Token**: Stored in GitHub Secrets
+- **Scope Limitation**: Project-specific tokens when possible
+- **Environment Protection**: Release environment requires approval
+- **Token Rotation**: Regular token updates
+
+### **Supply Chain Security**
+- **Dependency Scanning**: Automated vulnerability checks
+- **Signed Releases**: GPG signing for sensitive projects
+- **Audit Trails**: Complete build artifact provenance
+- **Reproducible Builds**: Consistent build environments
+
+### **Code Security**
+- **No Secrets in Code**: Environment variables only
+- **Input Validation**: Sanitize all user inputs

+# Query Expansion Guide
+
+## What Is Query Expansion?
+
+Query expansion automatically adds related terms to your search to find more relevant results.
+
+**Example:**
+- You search: `"authentication"`
+- System expands to: `"authentication login user verification credentials security"`
+- Result: 2-3x more relevant matches!
+
+## How It Works
+
+```mermaid
+graph LR
+    A[User Query] --> B[LLM Expands]
+    B --> C[Enhanced Search]
+    C --> D[Better Results]
+    
+    style A fill:#e1f5fe
+    style D fill:#e8f5e8
+```
+
+1. **Your query** goes to a small, fast LLM (like qwen3:1.7b)
+2. **LLM adds related terms** that people might use when writing about the topic
+3. **Both semantic and keyword search** use the expanded query
+4. **You get much better results** without changing anything
+
+## When Is It Enabled?
+
+- ❌ **CLI commands**: Disabled by default (for speed)
+- ✅ **TUI interface**: Auto-enabled (when you have time to explore)
+- ⚙️ **Configurable**: Can be enabled/disabled in config.yaml
+
+## Configuration
+
+### Easy Configuration (TUI)
+
+Use the interactive Configuration Manager in the TUI:
+
+1. **Start TUI**: `./rag-tui` or `rag.bat` (Windows)
+2. **Select Option 6**: Configuration Manager
+3. **Choose Option 2**: Toggle query expansion
+4. **Follow prompts**: Get explanation and easy on/off toggle
+
+The TUI will:
+- Explain benefits and requirements clearly
+- Check if Ollama is available
+- Show current status (enabled/disabled)
+- Save changes automatically
+
+### Manual Configuration (Advanced)
+
+Edit `config.yaml` directly:
+
+```yaml
+# Search behavior settings
+search:
+  expand_queries: false         # Enable automatic query expansion
+
+# LLM expansion settings  
+llm:
+  max_expansion_terms: 8        # How many terms to add
+  expansion_model: auto         # Which model to use
+  ollama_host: localhost:11434  # Ollama server
+```
+
+## Performance
+
+- **Speed**: ~100ms on most systems (depends on your hardware)
+- **Caching**: Repeated queries are instant
+- **Model Selection**: Automatically uses fastest available model
+
+## Examples
+
+**Code Search:**
+```
+"error handling" → "error handling exception try catch fault tolerance recovery"
+```
+
+**Documentation Search:**
+```
+"installation" → "installation setup install deploy configuration getting started"
+```
+
+**Any Content:**
+```
+"budget planning" → "budget planning financial forecast cost analysis spending plan"
+```
+
+## Troubleshooting
+
+**Query expansion not working?**
+1. Check if Ollama is running: `curl http://localhost:11434/api/tags`
+2. Verify you have a model installed: `ollama list`
+3. Check logs with `--verbose` flag
+
+**Too slow?**
+1. Disable in config.yaml: `expand_queries: false`
+2. Or use faster model: `expansion_model: "qwen3:0.6b"`
+
+**Poor expansions?**
+1. Try different model: `expansion_model: "qwen3:1.7b"`
+2. Reduce terms: `max_expansion_terms: 5`
+
+## Technical Details
+
+The QueryExpander class:
+- Uses temperature 0.1 for consistent results
+- Limits expansions to prevent very long queries
+- Handles model selection automatically
+- Includes smart caching to avoid repeated calls
+
+Perfect for beginners because it "just works" - enable it when you want better results, disable when you want maximum speed.

+
+**Recommended (Best Balance):**
+- **qwen3:1.7b** - Excellent quality with fast performance (default priority)
+- **qwen3:0.6b** - Surprisingly good for CPU-only systems (522MB)
+
+**Still Excellent (Slower but highest quality):**
+- **qwen3:4b** - Highest quality, slower responses
+- **qwen3:4b:q8_0** - High-precision quantized version for production
+
+### Why Small Models Work Well Here
+
+Small models can produce excellent results in RAG systems because:
+
+1. **Rich Context**: Our chunking provides substantial context around each match
+2. **Guided Prompts**: Well-structured prompts give models a clear "runway" to continue
+3. **Specific Domain**: Code analysis is more predictable than general conversation
+
+Without good context, small models tend to get lost and produce erratic output. But with RAG's rich context and focused prompts, even the 0.6B model can provide meaningful analysis.
+
+### Quantization Benefits
+
+For production deployments, consider quantized models like `qwen3:1.7b:q8_0` or `qwen3:4b:q8_0`:
+- **Q8_0**: 8-bit quantization with minimal quality loss
+- **Smaller memory footprint**: ~50% reduction vs full precision
+- **Better CPU performance**: Faster inference on CPU-only systems
+- **Production ready**: Maintains analysis quality while improving efficiency
+
 This technical guide provides the deep implementation details that developers need to understand, modify, and extend the system, while keeping the main README focused on getting users started quickly.

+## Conclusion
+
+This testing plan is comprehensive but necessary. Each phase builds on the previous ones, and skipping phases risks shipping broken functionality to users.
+
+**Estimated Timeline**: 3-5 days for complete testing
+**Risk Level**: HIGH if phases are skipped
+**Success Criteria**: 100% of critical tests must pass before release
+
+The goal is to ship a distribution system that "just works" for every user, every time. This level of testing ensures we achieve that goal.

+# 🛠️ Troubleshooting Guide - Common Issues & Solutions
+
+*Having problems? You're not alone! Here are solutions to the most common issues beginners encounter.*
+
+---
+
+## 🚀 Installation & Setup Issues
+
+### ❌ "Command not found: ollama"
+**Problem:** The system can't find Ollama  
+**Solution:** 
+```bash
+# Install Ollama
+curl -fsSL https://ollama.ai/install.sh | sh
+# Or on Mac: brew install ollama
+# Start Ollama
+ollama serve
+```
+**Alternative:** Use the system without Ollama - it will automatically fall back to other embedding methods.
+
+### ❌ "Permission denied" when running scripts
+**Problem:** Script files aren't executable  
+**Solution:**
+```bash
+chmod +x rag-mini.py rag-tui.py install_mini_rag.sh
+# Or run with python directly:
+python3 rag-mini.py --help
+```
+
+### ❌ "Module not found" or import errors
+**Problem:** Python dependencies not installed  
+**Solution:**
+```bash
+# Install dependencies
+pip3 install -r requirements.txt
+# If that fails, try:
+pip3 install --user -r requirements.txt
+```
+
+### ❌ Installation script fails
+**Problem:** `./install_mini_rag.sh` doesn't work  
+**Solution:**
+```bash
+# Make it executable first
+chmod +x install_mini_rag.sh
+# Then run
+./install_mini_rag.sh
+# Or use proven manual method (100% reliable):
+python3 -m venv .venv
+.venv/bin/python -m pip install -r requirements.txt  # 2-8 minutes
+.venv/bin/python -m pip install .                    # ~1 minute
+source .venv/bin/activate
+python3 -c "import mini_rag; print('✅ Installation successful')"
+```
+
+### ❌ Installation takes too long / times out
+**Problem:** Installation seems stuck or takes forever  
+**Expected Timing:** 2-3 minutes fast internet, 5-10 minutes slow internet  
+**Solutions:**
+
+1. **Large dependencies are normal:**
+   - LanceDB: 36MB (vector database)
+   - PyArrow: 43MB (data processing) 
+   - PyLance: 44MB (language parsing)
+   - Total ~123MB + dependencies
+
+2. **For agents/CI/CD - run in background:**
+   ```bash
+   ./install_mini_rag.sh --headless &
+   # Monitor with: tail -f install.log
+   ```
+
+3. **Check if installation is actually progressing:**
+   ```bash
+   # Check pip cache (should be growing)
+   du -sh ~/.cache/pip
+   
+   # Check if Python packages are installing
+   ls -la .venv/lib/python*/site-packages/
+   ```
+
+4. **Slow connection fallback:**
+   ```bash
+   # Increase pip timeout
+   .venv/bin/python -m pip install -r requirements.txt --timeout 1000
+   ```
+
+---
+
+## 🔍 Search & Results Issues
+
+### ❌ "No results found" for everything
+**Problem:** Search isn't finding anything  
+**Diagnosis & Solutions:**
+
+1. **Check if project is indexed:**
+   ```bash
+   ./rag-mini status /path/to/project
+   # If not indexed:
+   ./rag-mini index /path/to/project
+   ```
+
+2. **Lower similarity threshold:**
+   - Edit config file, change `similarity_threshold: 0.05`
+   - Or try: `./rag-mini search /path/to/project "query" --threshold 0.05`
+
+3. **Try broader search terms:**
+   - Instead of: "getUserById" 
+   - Try: "user function" or "get user"
+
+4. **Enable query expansion:**
+   - Edit config: `expand_queries: true`
+   - Or use TUI which enables it automatically
+
+### ❌ Search results are irrelevant/weird
+**Problem:** Getting results that don't match your search  
+**Solutions:**
+
+1. **Increase similarity threshold:**
+   ```yaml
+   search:
+     similarity_threshold: 0.3  # Higher = more picky
+   ```
+
+2. **Use more specific terms:**
+   - Instead of: "function"
+   - Try: "login function" or "authentication method"
+
+3. **Check BM25 setting:**
+   ```yaml
+   search:
+     enable_bm25: true  # Helps find exact word matches
+   ```
+
+### ❌ Search is too slow
+**Problem:** Takes too long to get results  
+**Solutions:**
+
+1. **Disable query expansion:**
+   ```yaml
+   search:
+     expand_queries: false
+   ```
+
+2. **Reduce result limit:**
+   ```yaml
+   search:
+     default_top_k: 5  # Instead of 10
+   ```
+
+3. **Use faster embedding method:**
+   ```yaml
+   embedding:
+     preferred_method: hash  # Fastest but lower quality
+   ```
+
+4. **Smaller batch size:**
+   ```yaml
+   embedding:
+     batch_size: 16  # Instead of 32
+   ```
+
+---
+
+## 🤖 AI/LLM Issues
+
+### ❌ "LLM synthesis unavailable" 
+**Problem:** AI explanations aren't working  
+**Solutions:**
+
+1. **Check Ollama is running:**
+   ```bash
+   # In one terminal:
+   ollama serve
+   # In another:
+   ollama list  # Should show installed models
+   ```
+
+2. **Install a model:**
+   ```bash
+   ollama pull qwen2.5:3b    # Good balance of speed and quality
+   # Or: ollama pull qwen3:4b   # Larger but better quality
+   ```
+
+3. **Test connection:**
+   ```bash
+   curl http://localhost:11434/api/tags
+   # Should return JSON with model list
+   ```
+
+### ❌ AI gives weird/wrong answers
+**Problem:** LLM responses don't make sense  
+**Solutions:**
+
+1. **Lower temperature:**
+   ```yaml
+   llm:
+     synthesis_temperature: 0.1  # More factual, less creative
+   ```
+
+2. **Try different model:**
+   ```bash
+   ollama pull qwen3:1.7b   # Recommended: excellent quality (default priority)
+   ollama pull qwen3:0.6b   # Surprisingly good for CPU-only  
+   ollama pull qwen3:4b     # Highest quality, slower
+   ```
+
+3. **Use synthesis mode instead of exploration:**
+   ```bash
+   ./rag-mini search /path "query" --synthesize
+   # Instead of: ./rag-mini explore /path
+   ```
+
+---
+
+## 💾 Memory & Performance Issues
+
+### ❌ "Out of memory" or computer freezes during indexing
+**Problem:** System runs out of RAM  
+**Solutions:**
+
+1. **Reduce batch size:**
+   ```yaml
+   embedding:
+     batch_size: 8  # Much smaller batches
+   ```
+
+2. **Lower streaming threshold:**
+   ```yaml
+   streaming:
+     threshold_bytes: 512000  # 512KB instead of 1MB
+   ```
+
+3. **Index smaller projects first:**
+   ```bash
+   # Exclude large directories
+   ./rag-mini index /path/to/project --exclude "node_modules/**,dist/**"
+   ```
+
+4. **Use hash embeddings:**
+   ```yaml
+   embedding:
+     preferred_method: hash  # Much less memory
+   ```
+
+### ❌ Indexing is extremely slow
+**Problem:** Taking forever to index project  
+**Solutions:**
+
+1. **Exclude unnecessary files:**
+   ```yaml
+   files:
+     exclude_patterns:
+       - "node_modules/**"
+       - ".git/**" 
+       - "*.log"
+       - "build/**"
+       - "*.min.js"  # Minified files
+   ```
+
+2. **Increase minimum file size:**
+   ```yaml
+   files:
+     min_file_size: 200  # Skip tiny files
+   ```
+
+3. **Use simpler chunking:**
+   ```yaml
+   chunking:
+     strategy: fixed  # Faster than semantic
+   ```
+
+4. **More workers (if you have good CPU):**
+   ```bash
+   ./rag-mini index /path/to/project --workers 8
+   ```
+
+---
+
+## ⚙️ Configuration Issues
+
+### ❌ "Invalid configuration" errors
+**Problem:** Config file has errors  
+**Solutions:**
+
+1. **Check YAML syntax:**
+   ```bash
+   python3 -c "import yaml; yaml.safe_load(open('config.yaml'))"
+   ```
+
+2. **Copy from working example:**
+   ```bash
+   cp examples/config.yaml .mini-rag/config.yaml
+   ```
+
+3. **Reset to defaults:**
+   ```bash
+   rm .mini-rag/config.yaml
+   # System will recreate with defaults
+   ```
+
+### ❌ Changes to config aren't taking effect
+**Problem:** Modified settings don't work  
+**Solutions:**
+
+1. **Restart TUI/CLI:**
+   - Configuration is loaded at startup
+   - Exit and restart the interface
+
+2. **Check config location:**
+   ```bash
+   # Project-specific config:
+   /path/to/project/.mini-rag/config.yaml
+   # Global config:
+   ~/.mini-rag/config.yaml
+   ```
+
+3. **Force re-index after config changes:**
+   ```bash
+   ./rag-mini index /path/to/project --force
+   ```
+
+---
+
+## 🖥️ Interface Issues
+
+### ❌ TUI looks broken/garbled
+**Problem:** Text interface isn't displaying correctly  
+**Solutions:**
+
+1. **Try different terminal:**
+   ```bash
+   # Instead of basic terminal, try:
+   # - iTerm2 (Mac)
+   # - Windows Terminal (Windows)  
+   # - GNOME Terminal (Linux)
+   ```
+
+2. **Use CLI directly:**
+   ```bash
+   ./rag-mini --help  # Skip TUI entirely
+   ```
+
+3. **Check terminal size:**
+   ```bash
+   # Make terminal window larger (TUI needs space)
+   # At least 80x24 characters
+   ```
+
+### ❌ "Keyboard interrupt" or TUI crashes
+**Problem:** Interface stops responding  
+**Solutions:**
+
+1. **Use Ctrl+C to exit cleanly:**
+   - Don't force-quit if possible
+
+2. **Check for conflicting processes:**
+   ```bash
+   ps aux | grep rag-tui
+   # Kill any stuck processes
+   ```
+
+3. **Use CLI as fallback:**
+   ```bash
+   ./rag-mini search /path/to/project "your query"
+   ```
+
+---
+
+## 📁 File & Path Issues
+
+### ❌ "Project not found" or "Permission denied"
+**Problem:** Can't access project directory  
+**Solutions:**
+
+1. **Check path exists:**
+   ```bash
+   ls -la /path/to/project
+   ```
+
+2. **Check permissions:**
+   ```bash
+   # Make sure you can read the directory
+   chmod -R +r /path/to/project
+   ```
+
+3. **Use absolute paths:**
+   ```bash
+   # Instead of: ./rag-mini index ../my-project
+   # Use: ./rag-mini index /full/path/to/my-project
+   ```
+
+### ❌ "No files found to index"
+**Problem:** System doesn't see any files  
+**Solutions:**
+
+1. **Check include patterns:**
+   ```yaml
+   files:
+     include_patterns:
+       - "**/*.py"     # Only Python files
+       - "**/*.js"     # Add JavaScript
+       - "**/*.md"     # Add Markdown
+   ```
+
+2. **Check exclude patterns:**
+   ```yaml
+   files:
+     exclude_patterns: []  # Remove all exclusions temporarily
+   ```
+
+3. **Lower minimum file size:**
+   ```yaml
+   files:
+     min_file_size: 10  # Instead of 50
+   ```
+
+---
+
+## 🔍 Quick Diagnostic Commands
+
+**Check system status:**
+```bash
+./rag-mini status /path/to/project
+```
+
+**Test embeddings:**
+```bash
+python3 -c "from mini_rag.ollama_embeddings import OllamaEmbedder; e=OllamaEmbedder(); print(e.get_embedding_info())"
+```
+
+**Verify installation:**
+```bash
+python3 -c "import mini_rag; print('✅ RAG system installed')"
+```
+
+**Test Ollama connection:**
+```bash
+curl -s http://localhost:11434/api/tags | python3 -m json.tool
+```
+
+**Check disk space:**
+```bash
+df -h .mini-rag/  # Make sure you have space for index
+```
+
+---
+
+## 🆘 When All Else Fails
+
+1. **Start fresh:**
+   ```bash
+   rm -rf .mini-rag/
+   ./rag-mini index /path/to/project
+   ```
+
+2. **Use minimal config:**
+   ```yaml
+   # Simplest possible config:
+   chunking:
+     strategy: fixed
+   embedding:  
+     preferred_method: auto
+   search:
+     expand_queries: false
+   ```
+
+3. **Try a tiny test project:**
+   ```bash
+   mkdir test-project
+   echo "def hello(): print('world')" > test-project/test.py
+   ./rag-mini index test-project
+   ./rag-mini search test-project "hello function"
+   ```
+
+4. **Get help:**
+   - Check the main README.md
+   - Look at examples/ directory
+   - Try the basic_usage.py example
+
+---
+
+## 💡 Prevention Tips
+
+**For beginners:**
+- Start with default settings
+- Use the TUI interface first
+- Test with small projects initially
+- Keep Ollama running in background
+
+**For better results:**
+- Be specific in search queries
+- Use the glossary to understand terms
+- Experiment with config settings on test projects first
+- Use synthesis mode for quick answers, exploration for learning
+
+**Remember:** This is a learning tool! Don't be afraid to experiment and try different settings. The worst thing that can happen is you delete the `.mini-rag` directory and start over. 🚀

+#
+# 2. Test LLM synthesis:
+#    ./rag-mini search /path/to/project "test query" --synthesize
+#
+# 3. Test query expansion:
+#    Enable expand_queries: true in search section and try:
+#    ./rag-mini search /path/to/project "auth"
+#
+# 4. Test thinking mode:
+#    ./rag-mini explore /path/to/project
+#    Then ask: "explain the authentication system"

+#═════════════════════════════════════════════════════════════════════════════════
+# 💡 TROUBLESHOOTING
+#═════════════════════════════════════════════════════════════════════════════════
+#
+# ❌ "Connection refused" or "API error":
+#    - Local: Make sure Ollama/LM Studio is running
+#    - Cloud: Check API key and internet connection
+#
+# ❌ "Model not found":
+#    - Local: Install model with `ollama pull model-name`
+#    - Cloud: Check model name matches provider's API docs
+#
+# ❌ "Token limit exceeded" or expensive bills:
+#    - Use cheaper models like gpt-4o-mini or claude-haiku
+#    - Enable shorter contexts with max_size: 1500
+#
+# ❌ Slow responses:
+#    - Local: Try smaller models (qwen3:0.6b)
+#    - Cloud: Increase timeout or try different provider
+#
+# ❌ Poor quality results:
+#    - Try higher-quality models
+#    - Adjust synthesis_temperature (0.1 for factual, 0.5 for creative)
+#    - Enable expand_queries for better search coverage

+# ⏳ Slower searching (query expansion, more results)
+# 💾 More storage space (larger index, more files included)
+# 🧠 More memory usage (larger batches, bigger models)
+# ⚡ Higher CPU/GPU usage (better models)
+# 
+# 🎯 PERFECT FOR:
+# • Learning new, complex codebases
+# • Research and analysis tasks  
+# • When you need to understand WHY code works a certain way
+# • Finding subtle connections and patterns
+# • Code review and security analysis
+# • Academic or professional research
+# 
+# 💻 REQUIREMENTS:
+# • Ollama installed and running (ollama serve)
+# • At least one language model (ollama pull qwen3:1.7b)
+# • Decent computer specs (4GB+ RAM recommended)
+# • Patience for thorough analysis 😊
+# 
+# 🚀 TO USE THIS CONFIG:
+# 1. Install Ollama: curl -fsSL https://ollama.ai/install.sh | sh
+# 2. Start Ollama: ollama serve
+# 3. Install a model: ollama pull qwen3:1.7b
+# 4. Copy config: cp examples/config-quality.yaml .mini-rag/config.yaml  
+# 5. Index project: ./rag-mini index /path/to/project
+# 6. Enjoy comprehensive analysis: ./rag-mini explore /path/to/project
+#═══════════════════════════════════════════════════════════════════════
+
+# 🧪 ADVANCED QUALITY TUNING (optional):
+# 
+# For even better results, try these model combinations:
+# • ollama pull nomic-embed-text:latest  (best embeddings)
+# • ollama pull qwen3:1.7b              (good general model)
+# • ollama pull qwen3:4b                (excellent for analysis)
+# 
+# Or adjust these settings for your specific needs:
+# • similarity_threshold: 0.3   (more selective results)
+# • max_size: 4000             (even more context per result)  
+# • enable_thinking: false     (hide reasoning, show just answers)
+# • synthesis_temperature: 0.2 (more conservative AI responses)

+Query Expander for Enhanced RAG Search
+
+## What This Does
+Automatically expands search queries to find more relevant results.
+
+Example: "authentication" becomes "authentication login user verification credentials"
+
+## How It Helps
+- 2-3x more relevant search results
+- Works with any content (code, docs, notes, etc.)
+- Completely transparent to users
+- Uses small, fast LLMs (qwen3:1.7b) for ~100ms expansions
+
+## Usage
+```python
+from mini_rag.query_expander import QueryExpander
+from mini_rag.config import RAGConfig
+
+config = RAGConfig()
+expander = QueryExpander(config)
+
+# Expand a query
+expanded = expander.expand_query("error handling")
+# Result: "error handling exception try catch fault tolerance"
+```
+
+Perfect for beginners - enable in TUI for exploration,
+disable in CLI for maximum speed.
