---|---|
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

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. |
Code to maintain and access indices.
