Description

As far as I can tell, you can't currently run a Full-text search and order by rank in SQLite.swift.

SELECT * FROM fts WHERE fts MATCH ? ORDER BY bm25(fts);
SELECT * FROM fts WHERE fts MATCH ? ORDER BY rank;

Is this feature currently available? If not, how do we order the results of a Full-text search by relevance? Is there currently a workaround?

Contributor guide

Research direction
Investigate how to implement ORDER BY rank in SQLite.swift's FTS queries, including support for bm25 or similar ranking functions. Look at existing FTS functionality and how to extend it.
