}Expand description
Features derived from BM25-style keyword matching.
Fields§
§term_frequency: Vec<(String, f64)>Per-term (term, tf_idf_contribution) pairs.
bm25_score: f64Aggregate BM25 score.
exact_match_bonus: f64+0.5 bonus when the whole query is an exact sub-string of the text.
length_penalty: f64Length penalty ∈ (-∞, 1.0]; penalises documents longer than average.
