of a term.
|
Class and Description |

CheckIndex.Status
Returned from
CheckIndex.checkIndex() detailing the health and status of the index. |
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 . |
IndexCommitPoint
Deprecated.
Please subclass IndexCommit class instead
|
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.MaxFieldLength
Specifies maximum field length in
IndexWriter constructors. |
LogMergePolicy
This class implements a
MergePolicy that tries
to merge segments into levels of exponentially
increasing size, where each level has < mergeFactor
segments in it. |
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 . |
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.
|
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. |
