impl<S: Scorer> Scorer for FilteredScorer<S>

fn doc_id(&self) -> DocId

Current document ID. Valid after next() or advance() has been called. Before the first call, the value is unspecified.

fn next(&mut self) -> DocId

Advance to the next matching document. Returns the new doc ID, or NO_MORE_DOCS if exhausted.

fn advance(&mut self, target: DocId) -> DocId

Advance to the first matching document at or after target. Returns the new doc ID, or NO_MORE_DOCS if no match >= target.

fn score(&mut self) -> f32

Score of the current document. Only meaningful when ScoreMode::needs_scores() is true.

fn two_phase(&mut self) -> Option<&mut dyn TwoPhaseIterator>

Optional two-phase iteration support.

fn max_score(&self) -> f32

Upper bound on the score this scorer can produce for any document. Used by WAND/MaxScore to skip non-competitive documents. Default: f32::MAX (no bound known).

fn block_max_score(&mut self, _doc: DocId) -> f32

Upper bound on score for documents in the block containing doc. Returns max_score() by default (no block-level information). Overridden by BlockMaxBm25Scorer for tighter per-block bounds.

fn set_min_competitive_score(&mut self, _min_score: f32)

Inform this scorer of the minimum competitive score. Documents scoring below this threshold may be skipped. Default: no-op.
