Class Summary

BooleanClause	A clause in a BooleanQuery.
BooleanQuery	A Query that matches documents matching boolean combinations of other queries, typically TermQuerys or PhraseQuerys.
CachingWrapperFilter	Wraps another filters result and caches it.
DateFilter	A Filter that restricts search results to a range of time.
DefaultSimilarity	Expert: Default scoring implementation.
Explanation	Expert: Describes the score computation for document and query.
FieldCache.StringIndex	Expert: Stores term text values and document ordering data.
FieldDoc	Expert: A ScoreDoc which also contains information about how to sort the referenced document.
Filter	Abstract base class providing a mechanism to restrict searches to a subset of an index.
FilteredQuery	A query that applies a filter to the results of another query.

MultiSearcher	Implements search over a set of Searchables.
MultiTermQuery	A Query that matches documents containing a subset of terms provided by a FilteredTermEnum enumeration.
ParallelMultiSearcher	Implements parallel search over a set of Searchables.
PhrasePrefixQuery	PhrasePrefixQuery is a generalized version of PhraseQuery, with an added method PhrasePrefixQuery.add(Term[]).
PhraseQuery	A Query that matches documents containing a particular sequence of terms.
PrefixQuery	A Query that matches documents containing terms with a specified prefix.
Query	The abstract base class for queries.
QueryFilter	Constrains search results to only match those which also match a provided query.
QueryTermVector
RangeQuery	A Query that matches documents within an exclusive range.
RemoteSearchable	A remote searchable implementation.
ScoreDoc	Expert: Returned by low-level search implementations.
Scorer	Expert: Implements scoring for a class of queries.
Searcher	An abstract base class for search implementations.
Similarity	Expert: Scoring API.
Sort	Encapsulates sort criteria for returned hits.
SortComparator	Abstract base class for sorting hits returned by a Query.
SortField	Stores information about how to sort documents by terms in an individual field.
TermQuery	A Query that matches documents containing a term.
TopDocs	Expert: Returned by low-level search implementations.
TopFieldDocs	Expert: Returned by low-level sorted search implementations.
WildcardQuery	Implements the wildcard search query.
WildcardTermEnum	Subclass of FilteredTermEnum for enumerating all terms that match the specified wildcard filter term.

Exception Summary

BooleanQuery.TooManyClauses

Thrown when an attempt is made to add more than BooleanQuery.getMaxClauseCount() clauses.
