          ## Installation Options
          ### 🚀 One-line installers (Recommended)
          **Linux/macOS:**
          ```bash
          curl -fsSL https://raw.githubusercontent.com/fsscoding/fss-mini-rag/main/install.sh | bash
          ```
          **Windows PowerShell:**
          ```powershell
          iwr https://raw.githubusercontent.com/fsscoding/fss-mini-rag/main/install.ps1 -UseBasicParsing | iex
          ```
          ### 📦 Manual installation
          **With uv (fastest):**
          ```bash
          uv tool install fss-mini-rag
          ```
          **With pipx:**
          ```bash
          pipx install fss-mini-rag
          ```
          **With pip:**
          ```bash
          pip install --user fss-mini-rag
          ```
          **Single file (no Python knowledge needed):**
          Download `rag-mini.pyz` and run with `python rag-mini.pyz`

 .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:

 <# Function declarations --------------------------------------------------- #>
 <#
 .Synopsis
 Remove all shell session elements added by the Activate script, including the
 addition of the virtual environment's Python executable from the beginning of
 the PATH variable.

 If present, do not remove this function from the global namespace for the
 session.

 .Description
 Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
 given folder, and returns them in a map.
 For each line in the pyvenv.cfg file, if that line can be parsed into exactly
 two strings separated by `=` (with any amount of whitespace surrounding the =)
 then it is considered a `key = value` line. The left hand string is the key,
 the right hand is the value.
 If the value starts with a `'` or a `"` then the first and last character is
 stripped from the value before being captured.
 .Parameter ConfigDir
 Path to the directory that contains the `pyvenv.cfg` file.

 # FSS-Mini-RAG Enhancement Backlog
 ## 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  
 rag-mini ../other "query"          # Relative path resolution
 ```
 ### Implementation Requirements
 1. **Auto-detect current working directory** when no path specified
 2. **Default to search command** when first argument is a query string
 3. **Proper path resolution** using `pathlib.Path.resolve()` for all relative paths
 4. **Maintain backwards compatibility** with existing explicit command syntax
 ### Technical Details
 - Modify `mini_rag/cli.py` argument parsing
 - Add path resolution with `os.path.abspath()` or `pathlib.Path.resolve()`
 - Make project_path optional (default to `os.getcwd()`)
 - Smart command detection (if first arg doesn't match command, assume search)
 ### Priority
 High - Significant UX improvement for daily usage

 **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."

 uv tool install fss-mini-rag      # Fastest
 pipx install fss-mini-rag         # Isolated
 pip install --user fss-mini-rag   # Traditional
 ```
 ### **2. Professional CI/CD Pipeline**
 - **Cross-platform wheel building** (Linux/Windows/macOS)
 - **Automated PyPI publishing** on release tags
 - **TestPyPI integration** for safe testing
 - **Release asset creation** with portable zipapp
 ### **3. Bulletproof Fallback System**
 Install scripts intelligently try:
 1. **uv** - Ultra-fast modern package manager
 2. **pipx** - Isolated tool installation  
 3. **pip** - Traditional Python package manager
 Each method is tested and verified before falling back to the next.
 ### **4. Multiple Distribution Formats**
 - **PyPI packages** (source + wheels) for standard installation
 - **Portable zipapp** (172.5 MB) for no-Python-knowledge users
 - **GitHub releases** with all assets automatically generated
 ## 🧪 **Testing Methodology**
 Our **"Option B: Proper Testing"** approach created:
 ### **Comprehensive Testing Framework**

 ## 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.

 - **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)
+**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
 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.

 - **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

 # 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.

 # 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
 ./rag-mini status ~/my-project
 ```
-## Step 3: Index Your First Project
+**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
-# Index any project directory
+# Linux/macOS
-./rag-mini index /path/to/your/project
+./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"
-# The system creates .mini-rag/ directory with:
+# Windows
-# - config.json (settings)
+rag.bat search C:\my-project "user authentication logic"  
-# - manifest.json (file tracking)  
+rag.bat search C:\my-project "error handling for database connections"
-# - database.lance/ (vector database)
+rag.bat search C:\my-project "how to validate input data"
 ```
-## Step 4: Search Your Code
+**Code concepts:**
 ```bash
-# Basic semantic search
+# Finds login functions, auth middleware, session handling
-./rag-mini search /path/to/project "user login logic"
+./rag-mini search ~/my-project "login functionality"
-# Enhanced search with smart features  
+# Finds try/catch blocks, error handlers, retry logic  
-./rag-mini-enhanced search /path/to/project "authentication"
+./rag-mini search ~/my-project "exception handling"
-# Find similar patterns
+# Finds validation functions, input sanitization, data checking
-./rag-mini-enhanced similar /path/to/project "def validate_input"
+./rag-mini search ~/my-project "data validation"
 ```
-## Step 5: Customize Configuration
+**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
-Edit `project/.mini-rag/config.json`:
+## Two Powerful Modes
-```json
+FSS-Mini-RAG has two different ways to get answers, optimized for different needs:
 {
  "chunking": {
    "max_size": 3000,
    "strategy": "semantic"  
  },
  "files": {
    "min_file_size": 100
  }
 }
 ```
-Then re-index to apply changes:
+### 🚀 **Synthesis Mode** - Fast Answers
 ```bash
-./rag-mini index /path/to/project --force
+# Linux/macOS
 ./rag-mini search ~/project "authentication logic" --synthesize
 # Windows  
 rag.bat search C:\project "authentication logic" --synthesize
 ```
-## Common Use Cases
+**Perfect for:**
 - Quick code discovery
 - Finding specific functions or patterns
 - Getting fast, consistent answers
-### Find Functions by Name
+**What you get:**
-```bash
+- Lightning-fast responses (no thinking overhead)
-./rag-mini search /project "function named connect_to_database" 
+- Reliable, factual information about your code
-```
+- Clear explanations of what code does and how it works
-### Find Code Patterns  
+### 🧠 **Exploration Mode** - Deep Understanding
 ```bash
 ./rag-mini search /project "error handling try catch"
 ./rag-mini search /project "database query with parameters"
 ```
 ### Find Configuration
 ```bash  
-./rag-mini search /project "database connection settings"
+# Linux/macOS
-./rag-mini search /project "environment variables"
+./rag-mini explore ~/project
 # Windows
 rag.bat explore C:\project
 ```
-### Find Documentation
+**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
-./rag-mini search /project "how to deploy" 
+# Linux/macOS  
-./rag-mini search /project "API documentation"
+./rag-mini status ~/my-project
 # Windows
 rag.bat status C:\my-project
 ```
-## Python API Usage
+**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
-```python
+## Configuration (Optional)
 from mini_rag import ProjectIndexer, CodeSearcher, CodeEmbedder
 from pathlib import Path
-# Initialize
+Your project gets a `.mini-rag/config.yaml` file with helpful comments:
 project_path = Path("/path/to/your/project")
 embedder = CodeEmbedder()
 indexer = ProjectIndexer(project_path, embedder)
 searcher = CodeSearcher(project_path, embedder)
-# Index the project
+```yaml
-print("Indexing project...")
+# Context window configuration (critical for AI features)
-result = indexer.index_project()
+# 💡 Sizing guide: 2K=1 question, 4K=1-2 questions, 8K=manageable, 16K=most users
-print(f"Indexed {result['files_processed']} files, {result['chunks_created']} chunks")
+#               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
-# Search
+# AI model preferences (edit to change priority)
-print("\nSearching for authentication code...")
+model_rankings:
-results = searcher.search("user authentication logic", limit=5)
+  - "qwen3:1.7b"    # Excellent for RAG (1.4GB, recommended)
-
+  - "qwen3:0.6b"    # Lightweight and fast (~500MB)  
-for i, result in enumerate(results, 1):
+  - "qwen3:4b"      # Higher quality but slower (~2.5GB)
    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
+**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
-### Auto-optimization
+## Troubleshooting
 ### "Project not indexed" 
 **Problem:** You're trying to search before indexing
 ```bash
-# Get optimization suggestions
+# Run indexing first
-./rag-mini-enhanced analyze /path/to/project
+./rag-mini index ~/my-project    # Linux/macOS
-
+rag.bat index C:\my-project      # Windows
 # This analyzes your codebase and suggests:
 # - Better chunk sizes for your language mix
 # - Streaming settings for large files
 # - File filtering optimizations
 ```
-### File Watching
+### "No Ollama models available"
-```python  
+**Problem:** AI features need models downloaded
-from mini_rag import FileWatcher
+```bash
 # Install Ollama first
 curl -fsSL https://ollama.ai/install.sh | sh    # Linux/macOS
 # Or download from https://ollama.com            # Windows
-# Watch for file changes and auto-update index
+# Start Ollama server
-watcher = FileWatcher(project_path, indexer)
+ollama serve
 watcher.start_watching()
-# Now any file changes automatically update the index
+# Download a model
 ollama pull qwen3:1.7b
 ```
-### Custom Chunking
+### "Virtual environment not found" 
-```python
+**Problem:** Auto-setup didn't work, need manual installation
 from mini_rag import CodeChunker
-chunker = CodeChunker()
+**Option A: Use installer scripts**
-
+```bash
-# Chunk a Python file
+./install_mini_rag.sh          # Linux/macOS  
-with open("example.py") as f:
+install_windows.bat            # Windows
    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
+**Option B: Manual method (100% reliable)**
 ```bash
 # 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
-### For Better Search Results
+# Windows  
- Use descriptive phrases: "function that validates email addresses" 
+python -m venv .venv
- Try different phrasings if first search doesn't work
+.venv\Scripts\python -m pip install -r requirements.txt  
- Search for concepts, not just exact variable names
+.venv\Scripts\python -m pip install .
 .venv\Scripts\activate.bat
 ```
-### For Better Indexing
+> **⏱️ Timing**: Fast internet 2-3 minutes total, slow internet 5-10 minutes due to large dependencies (LanceDB 36MB, PyArrow 43MB, PyLance 44MB).
 - Exclude build directories: `node_modules/`, `build/`, `dist/`
 - Include documentation files - they often contain valuable context
 - Use semantic chunking strategy for most projects
-### For Configuration  
+### Getting weird results
- Start with default settings
+**Solution:** Try different search terms or check what got indexed
- Use `analyze` command to get optimization suggestions
+```bash
- Increase chunk size for larger functions/classes
+# See what files were processed
- Decrease chunk size for more granular search
+./rag-mini status ~/my-project
-### For Troubleshooting
+# Try more specific queries
- Check `./rag-mini status` to see what was indexed
+./rag-mini search ~/my-project "specific function name"
- 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?
+## Next Steps
-1. Try the test suite to understand how components work:
+### Learn More
-   ```bash
+- **[Beginner's Glossary](BEGINNER_GLOSSARY.md)** - All the terms explained simply
-   python -m pytest tests/ -v
+- **[TUI Guide](TUI_GUIDE.md)** - Master the interactive interface
-   ```

 ## 🧪 Testing Your Setup
 ### 1. Basic Functionality Test
 ```bash
 # Test without LLM (should always work)
 ./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. 🚀

 #═════════════════════════════════════════════════════════════════════════════════
 # 🧪 TESTING YOUR CONFIGURATION
 #═════════════════════════════════════════════════════════════════════════════════
 #
 # 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

 # Larger chunks = more context but might be less precise
 # Text chunking settings

 # 🎯 QUICK TROUBLESHOOTING:
 # 
 # Search returns nothing? → Lower similarity_threshold to 0.05
 # Search too slow? → Set expand_queries: false and batch_size: 16  
 # Results not detailed enough? → Increase max_size to 3000
 # Getting weird fragments? → Check min_size is at least 150
 # AI not working? → Make sure Ollama is running: `ollama serve`
 # Out of memory errors? → Decrease batch_size to 16 and lower threshold_bytes

 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.
