Motivation
Full-Text Search version 5. A SQLite extension that enables fast text search. Hermes uses it for session search.
Concrete Example
FTS5: you search docker debugging. It finds all sessions containing docker or debugging. Ranked by relevance. Fast, like Google for your chats.
Analogy
A search engine index - it catalogs every word in every document. FTS5 catalogs every word in every session for fast search.
