Packages that use Collector
org.apache.lucene.search | Code to search indices.

Uses of Collector in org.apache.lucene.search

Subclasses of Collector in org.apache.lucene.search
`class` | `CachingCollector` Caches all docs, and optionally also scores, coming from a search, and is then able to replay them to another collector.
`class` | `MultiCollector` A `Collector` which allows running a search with several `Collector`s.
`class` | `PositiveScoresOnlyCollector` A `Collector` implementation which wraps another `Collector` and makes sure only documents with scores > 0 are collected.
`class` | `TimeLimitingCollector` The `TimeLimitingCollector` is used to timeout search requests that take longer than the maximum allowed search time limit.
`class` | `TopDocsCollector<T extends ScoreDoc>` A base class for all collectors that return a `TopDocs` output.
`class` | `TopFieldCollector` A `Collector` that sorts by `SortField` using `FieldComparator`s.
`class` | `TopScoreDocCollector` A `Collector` implementation that collects the top-scoring hits, returning them as a `TopDocs`.
`class` | `TotalHitCountCollector` Just counts the total number of hits.

Fields in org.apache.lucene.search declared as Collector
`protected Collector` | `CachingCollector.other`

Methods in org.apache.lucene.search that return Collector
`static Collector` | `MultiCollector.wrap(Collector... collectors)` Wraps a list of `Collector`s with a `MultiCollector`.

Methods in org.apache.lucene.search with parameters of type Collector
`static CachingCollector` | `CachingCollector.create(Collector other, boolean cacheScores, double maxRAMMB)` Create a new `CachingCollector` that wraps the given collector and caches documents and scores up to the specified RAM threshold.
`static CachingCollector` | `CachingCollector.create(Collector other, boolean cacheScores, int maxDocsToCache)` Create a new `CachingCollector` that wraps the given collector and caches documents and scores up to the specified max docs threshold.
`abstract void` | `CachingCollector.replay(Collector other)` Replays the cached doc IDs (and scores) to the given Collector.
`void` | `ConstantScoreQuery.ConstantScorer.score(Collector collector)`
`void` | `ScoreCachingWrappingScorer.score(Collector collector)`
`void` | `Scorer.score(Collector collector)` Scores and collects all matching documents.
`protected boolean` | `ConstantScoreQuery.ConstantScorer.score(Collector collector, int max, int firstDocID)`
`protected boolean` | `ScoreCachingWrappingScorer.score(Collector collector, int max, int firstDocID)`
`protected boolean` | `Scorer.score(Collector collector, int max, int firstDocID)` Expert: Collects matching documents in a range.
`void` | `Searcher.search(Query query, Collector results)` Deprecated. Lower-level search API.
`void` | `IndexSearcher.search(Query query, Collector results)` Lower-level search API.
`void` | `Searcher.search(Query query, Filter filter, Collector results)` Deprecated. Lower-level search API.
`void` | `IndexSearcher.search(Query query, Filter filter, Collector results)` Lower-level search API.
`void` | `MultiSearcher.search(Weight weight, Filter filter, Collector collector)` Deprecated.
`void` | `Searchable.search(Weight weight, Filter filter, Collector collector)` Deprecated. Lower-level search API.
`abstract void` | `Searcher.search(Weight weight, Filter filter, Collector results)` Deprecated.
`void` | `IndexSearcher.search(Weight weight, Filter filter, Collector collector)` Lower-level search API.
`void` | `ParallelMultiSearcher.search(Weight weight, Filter filter, Collector collector)` Deprecated. Lower-level search API.
`void` | `TimeLimitingCollector.setCollector(Collector collector)` This is so the same timer can be used with a multi-phase search process such as grouping.
`static Collector` | `MultiCollector.wrap(Collector... collectors)` Wraps a list of `Collector`s with a `MultiCollector`.

Constructors in org.apache.lucene.search with parameters of type Collector
`PositiveScoresOnlyCollector(Collector c)`
`TimeLimitingCollector(Collector collector, Counter clock, long ticksAllowed)` Create a TimeLimitedCollector wrapper over another `Collector` with a specified timeout.
