pub fn search_nodes(
conn: &Connection,
query: &str,
limit: usize,
) -> Result<Vec<GraphNode>>Expand description
Search nodes using FTS5 MATCH, ranked by BM25 relevance then importance.
The query is escaped as a phrase literal, so arbitrary user text is safe.
A malformed-query error is degraded to an empty result rather than an Err:
full-text is one signal among several in crate::graph::recall::smart_recall, and a bad hint must
not take down the whole recall.
