Uses of Scorer in org.apache.lucene.search

Classes in org.apache.lucene.search with type parameters of type Scorer
`static class` `Scorer.ScorerVisitor<P extends Query,C extends Query,S extends Scorer>` A callback to gather information from a scorer and its sub-scorers.

Subclasses of Scorer in org.apache.lucene.search
`protected class` `ConstantScoreQuery.ConstantScorer`
`class` `ScoreCachingWrappingScorer` A `Scorer` which wraps another scorer and caches the score of the current document.

Methods in org.apache.lucene.search that return Scorer
`Scorer` `ConstantScoreQuery.ConstantWeight.scorer(IndexReader reader, boolean scoreDocsInOrder, boolean topScorer)`
`Scorer` `BooleanQuery.BooleanWeight.scorer(IndexReader reader, boolean scoreDocsInOrder, boolean topScorer)`
`Scorer` `DisjunctionMaxQuery.DisjunctionMaxWeight.scorer(IndexReader reader, boolean scoreDocsInOrder, boolean topScorer)` Create the scorer used to score our associated DisjunctionMaxQuery
`abstract Scorer` `Weight.scorer(IndexReader reader, boolean scoreDocsInOrder, boolean topScorer)` Returns a `Scorer` which scores documents in/out-of order according to `scoreDocsInOrder`.

Methods in org.apache.lucene.search with parameters of type Scorer
`abstract void` `Collector.setScorer(Scorer scorer)` Called before successive calls to `Collector.collect(int)`.
`void` `PositiveScoresOnlyCollector.setScorer(Scorer scorer)`
`void` `FieldComparator.setScorer(Scorer scorer)` Sets the Scorer to use in case a document's score is needed.
`void` `FieldComparator.RelevanceComparator.setScorer(Scorer scorer)`
`void` `TotalHitCountCollector.setScorer(Scorer scorer)`
`void` `MultiCollector.setScorer(Scorer s)`
`void` `TimeLimitingCollector.setScorer(Scorer scorer)`
`void` `TopScoreDocCollector.setScorer(Scorer scorer)`

Method parameters in org.apache.lucene.search with type arguments of type Scorer
`void` `Scorer.visitScorers(Scorer.ScorerVisitor<Query,Query,Scorer> visitor)` Expert: call this to gather details for all sub-scorers for this query.
`void` `Scorer.visitSubScorers(Query parent, BooleanClause.Occur relationship, Scorer.ScorerVisitor<Query,Query,Scorer> visitor)` `Scorer` subclasses should implement this method if the subclass itself contains multiple scorers to support gathering details for sub-scorers via `Scorer.ScorerVisitor`

Constructors in org.apache.lucene.search with parameters of type Scorer
`ScoreCachingWrappingScorer(Scorer scorer)` Creates a new instance by wrapping the given scorer.

Uses of Scorer in org.apache.lucene.search.payloads

Subclasses of Scorer in org.apache.lucene.search.payloads
`class` `PayloadNearQuery.PayloadNearSpanScorer`
`protected class` `PayloadTermQuery.PayloadTermWeight.PayloadTermSpanScorer`

Methods in org.apache.lucene.search.payloads that return Scorer
`Scorer` `PayloadNearQuery.PayloadNearSpanWeight.scorer(IndexReader reader, boolean scoreDocsInOrder, boolean topScorer)`
`Scorer` `PayloadTermQuery.PayloadTermWeight.scorer(IndexReader reader, boolean scoreDocsInOrder, boolean topScorer)`

Uses of Scorer in org.apache.lucene.search.spans

Subclasses of Scorer in org.apache.lucene.search.spans
`class` `SpanScorer` Public for extension only.

Methods in org.apache.lucene.search.spans that return Scorer
`Scorer` `SpanWeight.scorer(IndexReader reader, boolean scoreDocsInOrder, boolean topScorer)`

`Scorer` `ScorerDocQueue.top()` Deprecated. Returns the least Scorer of the ScorerDocQueue in constant time.

Methods in org.apache.lucene.util with parameters of type Scorer
`boolean` `ScorerDocQueue.insert(Scorer scorer)` Deprecated. Adds a Scorer to the ScorerDocQueue in log(size) time if either the ScorerDocQueue is not full, or not lessThan(scorer, top()).
