Uses of MergePolicy in org.apache.lucene.index

Subclasses of MergePolicy in org.apache.lucene.index

class	BalancedSegmentMergePolicy Merge policy that tries to balance not doing large segment merges with not accumulating too many segments in the index, to provide for better performance in near real-time setting.
class	LogByteSizeMergePolicy This is a LogMergePolicy that measures size of a segment as the total byte size of the segment's files.
class	LogDocMergePolicy This is a LogMergePolicy that measures size of a segment as the number of documents (not taking deletions into account).
class	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.
class	MockRandomMergePolicy MergePolicy that makes random decisions for testing.
class	NoMergePolicy A MergePolicy which never returns merges to execute (hence it's name).
class	TieredMergePolicy Merges segments of approximately equal size, subject to an allowed number of segments per tier.
class	UpgradeIndexMergePolicy This MergePolicy is used for upgrading all existing segments of an index when calling IndexWriter.forceMerge(int).

Fields in org.apache.lucene.index declared as MergePolicy

protected MergePolicy	UpgradeIndexMergePolicy.base
static MergePolicy	NoMergePolicy.COMPOUND_FILES A singleton NoMergePolicy which indicates the index uses compound files.
static MergePolicy	NoMergePolicy.NO_COMPOUND_FILES A singleton NoMergePolicy which indicates the index does not use compound files.

Methods in org.apache.lucene.index that return MergePolicy

MergePolicy	IndexWriterConfig.getMergePolicy() Returns the current MergePolicy in use by this writer.
MergePolicy	IndexWriter.getMergePolicy() Deprecated. use IndexWriterConfig.getMergePolicy() instead

Methods in org.apache.lucene.index with parameters of type MergePolicy

IndexWriterConfig	IndexWriterConfig.setMergePolicy(MergePolicy mergePolicy) Expert: MergePolicy is invoked whenever there are changes to the segments in the index.
void	IndexWriter.setMergePolicy(MergePolicy mp) Deprecated. use IndexWriterConfig.setMergePolicy(MergePolicy) instead.

Constructors in org.apache.lucene.index with parameters of type MergePolicy

UpgradeIndexMergePolicy(MergePolicy base)
Wrap the given MergePolicy and intercept forceMerge requests to only upgrade segments written with previous Lucene versions.
