to merge segments into levels of exponentially
increasing size, where each level has < mergeFactor
segments in it. |

primitive merge operations to be used for overall merge
and optimize operations.
Whenever the segments in an index have been altered by
IndexWriter , either the addition of a newly
flushed segment, addition of many segments from
addIndexes* calls, or a previous merge that may now need
to cascade,
IndexWriter invokes
MergePolicy.findMerges to give the MergePolicy a chance to pick
merges that are now required. |

implementing this interface to execute the merges
selected by a
MergePolicy . |

| SortedTermVectorMapper.java | Class | Store a sorted collection of
org.apache.lucene.index.TermVectorEntry s. |
| StaleReaderException.java | Class | This exception is thrown when an
IndexReader tries to make changes to the index (via
IndexReader.deleteDocument ,
IndexReader.undeleteAll or
