Struct SearchConfig 

pub struct SearchConfig {
    pub default_limit: u32,
    pub max_limit: u32,
    pub min_relevance_score: Option<f64>,
    pub preview_max_chars: usize,
    pub preview_min_chars: usize,
    pub column_weights: BTreeMap<String, f64>,
}

Fields

default_limit: u32

max_limit: u32

min_relevance_score: Option<f64>

BM25 score cutoff. When set, only results with bm25() < threshold are returned. BM25 returns negative values for rare-term matches and positive values for common-term matches in large corpora. Example: Some(-0.3) drops near-zero noise in production. Default None means no threshold filtering (safe for small/test corpora).

preview_max_chars: usize

Preview length in chars for the best match (position 0).

preview_min_chars: usize

Preview length in chars for weak matches (position 3+).

column_weights: BTreeMap<String, f64>

Per-column BM25 weights. Keys are FTS5 column names; unknown keys are ignored. Defaults: key=10, value=1, tags=5, source_type=0.5, scope=0.5.
