Classes in org.apache.lucene.index used by org.apache.lucene.index

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

CheckIndex.Status.FieldNormStatus
Status from testing field norms.

CheckIndex.Status.SegmentInfoStatus
Holds the status of each segment in the index.

CheckIndex.Status.StoredFieldStatus
Status from testing stored fields.

CheckIndex.Status.TermIndexStatus
Status from testing term index.

CheckIndex.Status.TermVectorStatus
Status from testing stored fields.

ConcurrentMergeScheduler.MergeThread

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

FilterIndexReader.FilterTermDocs
Base class for filtering TermDocs implementations.

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

IndexDeletionPolicy
Expert: policy for deletion of stale index commits.

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

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

IndexReader.FieldOption
Constants describing field properties, for example used for IndexReader.getFieldNames(FieldOption).

IndexWriter
An IndexWriter creates and maintains an index.

IndexWriter.IndexReaderWarmer
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.

IndexWriter.MaxFieldLength
Specifies maximum field length (in number of tokens/terms) in IndexWriter constructors.

LogMergePolicy
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.

MergePolicy
Expert: a MergePolicy determines the sequence of primitive merge operations to be used for overall merge and optimize operations.

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

MergePolicy.OneMerge
OneMerge provides the information necessary to perform an individual primitive merge operation, resulting in a single new segment.

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

PositionBasedTermVectorMapper.TVPositionInfo
Container for a term at a position

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

SegmentInfos
A collection of segmentInfo objects with methods for operating on those segments in relation to the file system.

SegmentReader
NOTE: This API is new and still experimental (subject to change suddenly in the next release)

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.

Term
A Term represents a word from text.

TermDocs
TermDocs provides an interface for enumerating <document, frequency> pairs for a term.

TermEnum
Abstract class for enumerating terms.

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.

TermVectorEntry
Convenience class for holding TermVector information.

TermVectorMapper
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).

TermVectorOffsetInfo
The TermVectorOffsetInfo class holds information pertaining to a Term in a TermPositionVector's offset information.
