Release Notes: v0.3.1

This release focuses on improving the robustness and consistency of file pattern handling across various search strategies, as well as enhancing the internal file indexing structure for better stability.

---

Key Changes

Improved File Pattern Handling (Fixes #10)

• Addressed inconsistencies in how file_pattern parameters are handled across different search strategies (ugrep, ripgrep, ag, grep, basic).
• Ensures that file patterns like "src/*.py" work consistently, providing more reliable search results.
• Enhanced search_code_advanced tool docstring with detailed documentation on how each search tool handles file patterns and fuzzy matching.

Refactored File Index Structure

• Improved the internal file_index data structure to prevent KeyError crashes in the find_files tool.
• Ensures consistent representation of file and directory entries, making the indexing logic more maintainable.

Documentation Updates

• Refined README.md files (English and Chinese) for clarity and accuracy.
• Clarified tooling, improved setup instructions, and restructured usage examples for a better user experience.

v0.2.0: Major Refactoring and Advanced Search

Release v0.2.0: Major Refactoring and Advanced Search

🚀 Major Features

• Advanced Search: Added search_code_advanced tool with automatic detection of ripgrep > ag > grep
• Safe Fuzzy Search: Implemented word-boundary fuzzy matching without regex complexity
• Lazy Loading: Search tools are detected only when needed for better performance

🔧 Refactoring & Cleanup

• Code Deduplication: Eliminated ~70 lines of duplicate code between project_settings.py and server.py
• Centralized Constants: Created constants.py for shared configuration values
• Removed Invasive Features:
  • Automatic gitignore modification (was unnecessary)
  • README creation functionality (limited value)

🏗️ Architecture Improvements

• Lazy Loading: Search tool detection only occurs when advanced search is used
• Better Error Handling: Improved exception handling across the codebase
• Cleaner Separation: Better separation of concerns between settings and server logic

🛠️ Technical Details

• Search tool priority: ripgrep > ag > grep > basic search
• Safe pattern escaping prevents regex injection
• Backward compatibility maintained for existing functionality
• Settings stored alongside index files for better organization

📁 Files Changed

• src/code_index_mcp/constants.py (new)
• src/code_index_mcp/project_settings.py (major refactoring)
• src/code_index_mcp/server.py (enhanced with advanced search)

This release significantly improves code organization, adds powerful search capabilities, and removes unnecessary complexity while maintaining full backward compatibility.
