Uses of Package

API and code to convert text into indexable/searchable tokens.

The logical representation of a Document for indexing and searching.

A simple query parser implemented with JavaCC.

Programmatic control over documents scores.

The calculus of spans.

Some utility classes.

A Payload is metadata that can be stored together with each occurrence of a term.

A Payload is metadata that can be stored together with each occurrence of a term.

Controls how much information is stored in the postings lists.

Returned from CheckIndex.checkIndex() detailing the health and status of the index.

Holds the status of each segment in the index.

Status from testing term index.

Access to the Fieldable Info file that describes document fields and whether or not they are indexed.

Collection of FieldInfos (accessible by number or by name).

Expert: represents a single commit into an index as seen by the IndexDeletionPolicy or IndexReader.

Filename filter that accept filenames and extensions only created by Lucene.

A custom listener that's invoked when the IndexReader is closed.

If IndexWriter.getReader() has been called (ie, this writer is in near real-time mode), then after a merge completes, this class can be invoked to warm the reader on the newly merged segment, before the merge commits.

Holds all the configuration of IndexWriter.

This class implements a MergePolicy that tries to merge segments into levels of exponentially increasing size, where each level has fewer segments than the value of the merge factor.

A MergeSpecification instance provides the information necessary to perform multiple merges.

Expert: IndexWriter uses an instance implementing this interface to execute the merges selected by a MergePolicy.

Deprecated.

Returns a PayloadProcessorProvider.PayloadProcessor for a given Term which allows processing the payloads of different terms differently.

Information about a segment such as it's name, directory, and files related to the segment.

IndexReader implementation over a single segment.

An IndexDeletionPolicy that wraps around any other IndexDeletionPolicy and adds the ability to hold and later release snapshots of an index.

A Term represents a word from text.

Abstract class for enumerating terms.

TermPositions provides an interface for enumerating the <document, frequency, <position>* > tuples for a term.

The TermVectorMapper can be used to map Term Vectors into your own structure instead of the parallel array structure used by IndexReader.getTermFreqVector(int,String).

Merges segments of approximately equal size, subject to an allowed number of segments per tier.

A Term represents a word from text.

This exception is thrown when Lucene detects an inconsistency in the index.

IndexReader is an abstract class, providing an interface for accessing an index.
