Description

Interface Summary

IndexCommitPoint	Expert: represents a single commit into an index as seen by the IndexDeletionPolicy.
IndexDeletionPolicy	Expert: policy for deletion of stale index commits.
TermDocs	TermDocs provides an interface for enumerating <document, frequency> pairs for a term.
TermFreqVector	Provides access to stored term vector of a document field.
TermPositions	TermPositions provides an interface for enumerating the <document, frequency, <position>* > tuples for a term.
TermPositionVector	Extends TermFreqVector to provide additional information about positions in which each of the terms is found.

Class Summary

FieldNormModifier	Given a directory and a list of fields, updates the fieldNorms in place for every document.
FilterIndexReader	A FilterIndexReader contains another IndexReader, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterIndexReader.FilterTermDocs	Base class for filtering TermDocs implementations.
FilterIndexReader.FilterTermEnum	Base class for filtering TermEnum implementations.
FilterIndexReader.FilterTermPositions	Base class for filtering TermPositions implementations.
IndexFileNameFilter	Filename filter that accept filenames and extensions only created by Lucene.
IndexModifier	[Note that as of 2.1, all but one of the methods in this class are available via IndexWriter.
IndexReader	IndexReader is an abstract class, providing an interface for accessing an index.
IndexReader.FieldOption
IndexWriter	An IndexWriter creates and maintains an index.
KeepOnlyLastCommitDeletionPolicy	This IndexDeletionPolicy implementation that keeps only the most recent commit and immediately removes all prior commits after a new commit is done.
MultipleTermPositions	Describe class MultipleTermPositions here.
MultiReader	An IndexReader which reads multiple indexes, appending their content.
ParallelReader	An IndexReader which reads multiple, parallel indexes.
Payload	A Payload is metadata that can be stored together with each occurrence of a term.
Term	A Term represents a word from text.
TermEnum	Abstract class for enumerating terms.
TermVectorOffsetInfo	The TermVectorOffsetInfo class holds information pertaining to a Term in a TermPositionVector's offset information.

Exception Summary

CorruptIndexException	This exception is thrown when Lucene detects an inconsistency in the index.
FieldReaderException
StaleReaderException	This exception is thrown when an IndexReader tries to make changes to the index (via IndexReader.deleteDocument(int), IndexReader.undeleteAll() or IndexReader.setNorm(int, java.lang.String, byte)) but changes have already been committed to the index since this reader was instantiated.
