How It Works

1. Documentation Download: On first run, downloads Expo documentation from GitHub (expo/expo repository)
2. Local Indexing: Builds a searchable index of all documentation files with metadata extraction
3. Fuzzy Search: Provides multiple search strategies including exact matching, partial matching, and fuzzy search
4. Smart Caching: Caches search results and content for 1 week to improve performance
5. Offline Operation: Works entirely offline after initial documentation download
