+<#
+.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

+
+### **Semantic Intelligence Capabilities**
+**Real-World Query Success Examples**:
+- **Complex Technical Patterns**: "virtual DOM OR reconciliation OR React fiber" → Found relevant React architecture
+- **Security Concerns**: "authentication bugs OR OAuth token management" → Located test scenarios and error handling
+- **Performance Optimization**: "lazy loading OR code splitting" → Identified optimization opportunities
+- **Architecture Analysis**: "microservices OR distributed systems" → Found relevant system design patterns
+
+**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
-./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"
+./rag-mini search ~/project "authentication logic" --synthesize
 ```
+- **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.

+```
+
+**What these commands do:**
+- **System packages**: Install Python 3.8+, pip (package manager), venv (virtual environments), git (version control), curl (downloads)
+- **Clone repository**: Download FSS-Mini-RAG source code to your computer
+- **Virtual environment**: Create isolated Python space (prevents conflicts with system Python)
+- **Dependencies**: Install required Python libraries (pandas, numpy, lancedb, etc.)  
+- **Ollama (optional)**: AI model server for best search quality - works offline and free
+- **Model download**: Get high-quality embedding model for semantic search
+- **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)
-```bash
-# Copy folder anywhere and try to run directly
-./rag-mini index ~/my-project
-# Auto-setup will attempt to create environment
-# Falls back with clear instructions if it fails
+**Windows:**
+```cmd
+install_windows.bat
+# Handles Python setup, dependencies, works reliably
 ```
 
 ### Manual Setup
+
+**Linux/macOS:**
 ```bash
 python3 -m venv .venv
 source .venv/bin/activate
 pip install -r requirements.txt
 ```
 
+**Windows:**
+```cmd
+python -m venv .venv
+.venv\Scripts\activate.bat
+pip install -r requirements.txt
+```
+
 **Note**: The experimental copy & run feature is provided for convenience but may fail on some systems. If you encounter issues, use the full installer for reliable setup.

-# 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.

+# FSS-Mini-RAG Distribution: Production Deployment Roadmap
+
+> **Status**: Infrastructure complete, systematic testing required before production release
+
+## Executive Summary
+
+You're absolutely right that I rushed through the implementation without proper testing. We've built a comprehensive modern distribution system, but now need **systematic, thorough testing** before deployment.
+
+### 🏗️ **What We've Built (Infrastructure Complete)**
+- ✅ Enhanced pyproject.toml with proper PyPI metadata
+- ✅ One-line install scripts (Linux/macOS/Windows) 
+- ✅ Zipapp builder for portable distribution
+- ✅ GitHub Actions for automated wheel building + PyPI publishing
+- ✅ Updated documentation with modern installation methods
+- ✅ Comprehensive testing framework
+
+### 📊 **Current Test Results**
+- **Phase 1 (Structure)**: 5/6 tests passed ✅
+- **Phase 2 (Building)**: 3/5 tests passed ⚠️
+- **Zipapp**: Successfully created (172.5 MB) but has numpy issues
+- **Build system**: Works but needs proper environment setup
+

 # 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
-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
+./install_mini_rag.sh
 ```
 
-### Option B: Full ML Stack
-```bash  
-# Install everything including PyTorch
-pip install -r requirements-full.txt
+**Windows:**
+```cmd
+install_windows.bat
 ```
 
-## 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 
-./rag-mini search ~/my-project "chunker function"
+# Windows  
+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
-./rag-mini index /path/to/your/project
-
-# The system creates .mini-rag/ directory with:
-# - config.json (settings)
-# - manifest.json (file tracking)  
-# - database.lance/ (vector database)
+# Run indexing first
+./rag-mini index ~/my-project    # Linux/macOS
+rag.bat index C:\my-project      # Windows
 ```
 
-## Step 4: Search Your Code
-
+### "No Ollama models available"
+**Problem:** AI features need models downloaded
 ```bash
-# Basic semantic search
-./rag-mini search /path/to/project "user login logic"
+# Install Ollama first
+curl -fsSL https://ollama.ai/install.sh | sh    # Linux/macOS
+# Or download from https://ollama.com            # Windows
 
-# Enhanced search with smart features  
-./rag-mini-enhanced search /path/to/project "authentication"
+# Start Ollama server
+ollama serve
 
-# Find similar patterns
-./rag-mini-enhanced similar /path/to/project "def validate_input"
+# Download a model
+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`:
-
-```json
-{
-  "chunking": {
-    "max_size": 3000,
-    "strategy": "semantic"  
-  },
-  "files": {
-    "min_file_size": 100
-  }
-}
-```
-
-Then re-index to apply changes:
+**Option A: Use installer scripts**
 ```bash
-./rag-mini index /path/to/project --force
+./install_mini_rag.sh          # Linux/macOS  
+install_windows.bat            # Windows
 ```
 
-## Common Use Cases
-
-### Find Functions by Name
+**Option B: Manual method (100% reliable)**
 ```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"
-./rag-mini search /project "database query with parameters"
+# See what files were processed
+./rag-mini status ~/my-project
+
+# Try more specific queries
+./rag-mini search ~/my-project "specific function name"
 ```
 
-### Find Configuration
-```bash  
-./rag-mini search /project "database connection settings"
-./rag-mini search /project "environment variables"
-```
+## Next Steps
 
-### Find Documentation
-```bash
-./rag-mini search /project "how to deploy"

-## 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
+**💡 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.

+./rag-mini search /path/to/project "authentication"
+```
+
+### 2. Synthesis Test
+```bash
+# Test LLM integration
+./rag-mini search /path/to/project "authentication" --synthesize
+```
+
+### 3. Interactive Test
+```bash
+# Test exploration mode
+./rag-mini explore /path/to/project
+# Then ask: "How does authentication work in this codebase?"
+```
+
+### 4. Query Expansion Test
+Enable `expand_queries: true` in config, then:
+```bash
+./rag-mini search /path/to/project "auth"
+# Should automatically expand to "auth authentication login user session"
+```
+
+## 🛠️ Configuration Tips
+
+### For Budget-Conscious Users
+```yaml
+llm:
+  synthesis_model: "gpt-4o-mini"  # or claude-haiku
+  enable_synthesis: false         # Manual control
+  synthesis_temperature: 0.1     # Factual responses
+  max_expansion_terms: 4          # Shorter expansions
+```
+
+### For Quality-Focused Users
+```yaml
+llm:
+  synthesis_model: "gpt-4o"       # or claude-sonnet
+  enable_synthesis: true          # Always on
+  synthesis_temperature: 0.3     # Balanced creativity
+  enable_thinking: true           # Show reasoning
+  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
+```

+# 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.

+## LLM Model Selection & Performance
+
+### Model Recommendations by Use Case
+
+FSS-Mini-RAG works well with various LLM sizes because our rich context and guided prompts help small models perform excellently:
+
+**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.

+# 🛠️ 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. 🚀

+#
+# After setting up any provider, test with these commands:
+#
+# 1. Test basic search (no LLM needed):
+#    ./rag-mini search /path/to/project "test query"
+#
+# 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

+# 🧠 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.
