A simple query parser implemented with JavaCC.

Programmatic control over documents scores.

The calculus of spans.

Expert: Scoring API.

Specifies how clauses are to occur in matching documents.

MultiPhraseQuery is a generalized version of PhraseQuery, with an added method MultiPhraseQuery.add(Term[]).

A Query that matches documents containing a particular sequence of terms.

Specifies how clauses are to occur in matching documents.

Caches all docs, and optionally also scores, coming from a search, and is then able to replay them to another collector.

Expert: Collectors are primarily meant to be used to gather raw results from a search, and implement sorting or custom result filtering, collation, etc.

This abstract class defines methods to iterate over a set of non-decreasing doc ids.

Small Util class used to pass both an idf factor as well as an explanation for that factor.

Interface to parse bytes from document fields.

Interface to parse doubles from document fields.

Interface to parse ints from document fields.

Marker interface as super-interface to all parsers.

Expert: Stores term text values and document ordering data.

Expert: a FieldComparator compares hits so as to determine their sort order when collecting the top results with TopFieldCollector.

Provides a FieldComparator for custom field sorting.

Abstract class for enumerating a subset of all terms.

Keeps the cache from getting too big.

Implements search over a single IndexReader.

An abstract Query that matches documents containing a subset of terms provided by a FilteredTermEnum enumeration.

A wrapper for MultiTermQuery, that exposes its functionality as a Filter.

Class that tracks changes to a delegated IndexWriter.

A Filter that only accepts numeric values within a specified range.

A Query that matches documents containing a particular sequence of terms.

Utility class to safely share instances of a certain type across multiple threads, while periodically refreshing them.

Expert: Common scoring functionality for different types of queries.

Deprecated.

See SearcherLifetimeManager.prune(org.apache.lucene.search.SearcherLifetimeManager.Pruner).

Abstract base class providing a mechanism to restrict searches to a subset of an index and also maintains and returns position information.

A Filter that restricts search results to a range of term values in a given field.

Represents hits returned by Searcher.search(Query,Filter,int) and Searcher.search(Query,int).

A Collector that sorts by SortField using FieldComparators.

A Collector implementation that collects the top-scoring hits, returning them as a TopDocs.

Expert: Calculate query weights and build query scorers.

Expert: Maintains caches of term values.
