Constructor

	IndexSearcher(IndexReader r) Creates a searcher searching the provided index.
	IndexSearcher(IndexReaderContext context) Creates a searcher searching the provided top-level IndexReaderContext .
	IndexSearcher(IndexReader r, Executor executor) Runs searches for each segment separately, using the provided Executor.

Method

CollectionStatistics	collectionStatistics(String field) Returns CollectionStatistics for a field, or null if the field does not exist (has no indexed terms) This can be overridden for example, to return a field's statistics across a distributed collection.
int	count(Query query) Count how many documents match the given query.
Weight	createWeight(Query query, ScoreMode scoreMode, float boost) Creates a Weight for the given query, potentially adding caching if possible and configured.
Document	doc(int docID) Sugar for `.getIndexReader().document(docID)`
void	doc(int docID, StoredFieldVisitor fieldVisitor) Sugar for `.getIndexReader().document(docID, fieldVisitor)`
Document	doc(int docID, Set fieldsToLoad) Sugar for `.getIndexReader().document(docID, fieldsToLoad)`
Explanation	explain(Query query, int doc) Returns an Explanation that describes how `doc` scored against `query`.
Explanation	explain(Weight weight, int doc) Expert: low-level implementation method Returns an Explanation that describes how `doc` scored against `weight`.
QueryCache	getDefaultQueryCache() Expert: Get the default QueryCache or null if the cache is disabled.
QueryCachingPolicy	getDefaultQueryCachingPolicy() Expert: Get the default QueryCachingPolicy .
IndexReader	getIndexReader() Return the IndexReader this searches.
QueryCache	getQueryCache() Return the query cache of this IndexSearcher .
QueryCachingPolicy	getQueryCachingPolicy() Return the query cache of this IndexSearcher .
Similarity	getSimilarity() Expert: Get the Similarity to use to compute scores.
IndexReaderContext	getTopReaderContext() Returns this searchers the top-level IndexReaderContext .
Query	rewrite(Query original) Expert: called to re-write queries into primitive queries.
TopDocs	search(Query query, int n) Finds the top `n` hits for `query`.
void	search(Query query, Collector results) Lower-level search API.
T	search(Query query, CollectorManager collectorManager) Lower-level search API.
TopFieldDocs	search(Query query, int n, Sort sort) Search implementation with arbitrary sorting.
void	search(List leaves, Weight weight, Collector collector) Lower-level search API.
TopFieldDocs	search(Query query, int n, Sort sort, boolean doDocScores) Search implementation with arbitrary sorting, plus control over whether hit scores and max score should be computed.
TopDocs	searchAfter(ScoreDoc after, Query query, int numHits) Finds the top `n` hits for `query` where all results are after a previous result (`after`).
TopDocs	searchAfter(ScoreDoc after, Query query, int n, Sort sort) Finds the top `n` hits for `query` where all results are after a previous result (`after`).
void	setDefaultQueryCachingPolicy(QueryCachingPolicy defaultQueryCachingPolicy) Expert: set the default QueryCachingPolicy instance.
void	setQueryCache(QueryCache queryCache) Set the QueryCache to use when scores are not needed.
void	setQueryCachingPolicy(QueryCachingPolicy queryCachingPolicy) Set the QueryCachingPolicy to use for query caching.
void	setSimilarity(Similarity similarity) Expert: Set the Similarity implementation used by this IndexSearcher.
TermStatistics	termStatistics(Term term, TermStates context) Returns TermStatistics for a term, or null if the term does not exist.
