Subject [jira] Created: (LUCENE-879) Document number integrity merge policy
Date Fri, 11 May 2007 17:20:15 GMT
Document number integrity merge policy
--------------------------------------

                 Key: LUCENE-879
                 URL: https://issues.apache.org/jira/browse/LUCENE-879
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Store
    Affects Versions: 2.1
            Reporter: Karl Wettin
            Priority: Minor
         Attachments: LUNCENE-879.diff

This patch allows for document numbers stays the same even after merge of segments with deletions.

Consumer needs to do this:
indexWriter.setSkipMergingDeletedDocuments(false);

The effect will be that deleted documents are replaced by a new Document() in the merged segment,
but not marked as deleted. This should probably be some policy thingy that allows for different
solutions such as keeping the old document, et c.
