Trait Searcher 

pub trait Searcher: Send + Sync {
    // Required method
    fn search(
        &self,
        query: &str,
        scope: Option<&str>,
        limit: usize,
    ) -> Result<Vec<ScoredEntry>>;
}

Trait for searching context entries by relevance.

Implementations must be thread-safe (Send + Sync) to support concurrent access from multiple worker threads.

Required Methods

fn search( &self, query: &str, scope: Option<&str>, limit: usize, ) -> Result<Vec<ScoredEntry>>

Search for entries matching query, optionally restricted to scope, returning at most limit results ordered by descending relevance score.

scope = None searches every entry regardless of scope (global recall). scope = Some(s) restricts results to entries whose scope equals s.

query is treated as natural-language text: implementations should split it into terms and OR-match them (e.g. via FTS5 bm25 ranking) rather than requiring every term to match. Query-language operator syntax (AND, OR, NEAR, prefix *, quoted phrases, column filters, etc.) must not be interpreted from query — operator characters are treated as term separators, so arbitrary text never produces a syntax error. A query with no usable terms (empty or punctuation-only) returns an empty result set, not an error. The special value crate::engine::MATCH_ALL_QUERY ("*") matches every entry.

Errors

Returns an error if the underlying search fails.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
