# Search & Indexing (Rule) When modifying search behavior, ranking, or index builds. ## Search Architecture (BM25-Only) - **Index Build**: `scripts/build-index.ts` → `dist/data/index.json` - **FTS Database**: `scripts/build-fts.ts` → `dist/data/docs.sqlite` - **Search Logic**: Pure BM25 via `src/lib/search.ts` using metadata APIs - **Query Processing**: `toMatchQuery()` in `src/lib/searchDb.ts` - **Configuration**: All source settings in `src/metadata.json` ## Metadata-Driven Configuration - **Source Boosts**: Context-aware scoring via `getContextBoosts()` - **Library Mappings**: ID resolution via `getAllLibraryMappings()` - **URL Generation**: Documentation links via `getDocUrlConfig()` - **Source Paths**: File system paths via `getSourcePath()` ## Key Search Features - **OR Logic**: Better recall for multi-term queries - **Prefix Matching**: Terms get `*` suffix for broader matching - **Phrase Queries**: Dotted terms (sap.m.Button) quoted for exact match - **Context Awareness**: UI5/CAP/wdi5 context detection and scoring ## Performance - **FTS5**: SQLite full-text search for sub-second response times - **Centralized Config**: Single metadata load at startup - **Efficient APIs**: Type-safe configuration access @file scripts/build-index.ts @file scripts/build-fts.ts @file src/lib/searchDb.ts @file src/lib/search.ts @file src/lib/metadata.ts @file src/metadata.json @file src/lib/localDocs.ts @file docs/ARCHITECTURE.md @file docs/DEV.md
