# `SuperPi.Memory.Search.FTS5`
[🔗](https://github.com/oleksandr/super-pi-beam/blob/v0.1.0/lib/super_pi/memory/search/fts5.ex#L1)

SQLite backend: the `memories_fts` FTS5 table, ranked by `bm25()` (title 10, topics 5, body 1).

The table is an external-content index that triggers keep in step with `memories`, so a note is
searchable in the transaction that wrote it. Words reach `MATCH` as quoted terms joined by `OR`.
Limit: the `unicode61` tokenizer splits on anything that is not a letter or digit, so it does not
segment languages written without spaces; a CJK note matches as one long token.
