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.
