Implementations§

Source§

impl MultiFieldBayesianScorer

Source

pub fn new( field_configs: Vec<FieldConfig>, stats: &Arc<IndexStats>, ) -> ScoringResult<Self>

Source

pub fn score_document( &self, term_freq_per_field: &BTreeMap<String, u64>, doc_length_per_field: &BTreeMap<String, u64>, doc_freq_per_field: &BTreeMap<String, u64>, ) -> f64

Score one document. Each *_per_field map keys on field name and yields the term frequency / document length / document frequency for that field. Missing fields contribute sparse absence rather than a synthetic probability.
