Uses of Searcher in org.apache.lucene.search

Subclasses of Searcher in org.apache.lucene.search

class	AssertingIndexSearcher Helper class that adds some extra checks to ensure correct usage of IndexSearcher and Weight.
static class	CheckHits.ExplanationAssertingSearcher an IndexSearcher that implicitly checks hte explanation of every match whenever it executes a search.
class	IndexSearcher Implements search over a single IndexReader.
class	MultiSearcher Deprecated. If you are using MultiSearcher over IndexSearchers, please use MultiReader instead; this class does not properly handle certain kinds of queries (see LUCENE-2756).
class	ParallelMultiSearcher Deprecated. Please pass an ExecutorService to IndexSearcher, instead.

Methods in org.apache.lucene.search with parameters of type Searcher

static void	QueryUtils.check(Random random, Query q1, Searcher s) Various query sanity checks on a searcher, some checks are only done for instanceof IndexSearcher.
static void	QueryUtils.check(Random random, Query q1, Searcher s, boolean wrap)
static void	QueryUtils.checkExplanations(Query q, Searcher s) deep check that explanations of a query 'score' correctly
static void	CheckHits.checkExplanations(Query query, String defaultFieldName, Searcher searcher) Asserts that the explanation value for every document matching a query corresponds with the true score.
static void	CheckHits.checkExplanations(Query query, String defaultFieldName, Searcher searcher, boolean deep) Asserts that the explanation value for every document matching a query corresponds with the true score.
static void	CheckHits.checkHitCollector(Random random, Query query, String defaultFieldName, Searcher searcher, int[] results) Tests that a query matches the an expected set of documents using a HitCollector.
static void	CheckHits.checkHits(Random random, Query query, String defaultFieldName, Searcher searcher, int[] results) Tests that a query matches the an expected set of documents using Hits.
static void	CheckHits.checkNoMatchExplanations(Query q, String defaultFieldName, Searcher searcher, int[] results) Tests that all documents up to maxDoc which are *not* in the expected result set, have an explanation which indicates that the document does not match
Weight	ConstantScoreQuery.createWeight(Searcher searcher)
Weight	DisjunctionMaxQuery.createWeight(Searcher searcher) Create the Weight used to score us
Weight	MatchAllDocsQuery.createWeight(Searcher searcher)
Weight	BooleanQuery.createWeight(Searcher searcher)
Weight	TermQuery.createWeight(Searcher searcher)
Weight	MultiPhraseQuery.createWeight(Searcher searcher)
Weight	PhraseQuery.createWeight(Searcher searcher)
Weight	FilteredQuery.createWeight(Searcher searcher) Returns a Weight that applies the filter to the enclosed query's Weight.
Weight	Query.createWeight(Searcher searcher) Expert: Constructs an appropriate Weight implementation for this query.
Similarity	Query.getSimilarity(Searcher searcher) Deprecated. Instead of using "runtime" subclassing/delegation, subclass the Weight instead.
Explanation.IDFExplanation	Similarity.idfExplain(Collection<Term> terms, Searcher searcher) Computes a score factor for a phrase.
Explanation.IDFExplanation	Similarity.idfExplain(Term term, Searcher searcher) This method forwards to Similarity.idfExplain(Term,Searcher,int) by passing searcher.docFreq(term) as the docFreq.
Explanation.IDFExplanation	Similarity.idfExplain(Term term, Searcher searcher, int docFreq) Computes a score factor for a simple term and returns an explanation for that score factor.
Weight	Query.weight(Searcher searcher) Deprecated. never ever use this method in Weight implementations. Subclasses of Query should use Query.createWeight(org.apache.lucene.search.Searcher), instead.
static MultiSearcher	QueryUtils.wrapSearcher(Random random, Searcher s, int edge) Given a Searcher, returns a new MultiSearcher wrapping the the original Searcher, as well as several "empty" IndexSearchers -- some of which will have deleted documents in them.
