Module text_search 

Full-text search re-exports from nodedb-fts.

Query-layer code that needs BM25 scoring, analyzers, or fuzzy matching imports from here. The implementation lives in the shared nodedb-fts crate.

Lite: uses engine::fts::FtsCollectionManager (wraps FtsIndex<MemoryBackend>). Origin: uses engine::sparse::fts_redb (wraps FtsIndex<RedbBackend>).
