[jira] [Commented] (LUCENE-3403) Term vectors missing after
addIndexes + optimize
[ https://issues.apache.org/jira/browse/LUCENE-3403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13091660#comment-13091660 ]
Simon Willnauer commented on LUCENE-3403:
-----------------------------------------
good catch Shai, Does this happen on 4.0 too? I don't think we have setHasVectors there anymore. I am just wondering since you put 4.0 as a fix version.

> I encountered a problem with addIndexes where term vectors disappeared following optimize(). I wrote a simple test case which demonstrates the problem. The bug appears with both addIndexes() versions, but does not appear if addDocument is called twice, committing changes in between.
> I think I tracked the problem down to IndexWriter.mergeMiddle() -- it sets term vectors before merger.merge() was called. In the addDocs case, merger.fieldInfos is already populated, while in the addIndexes case it is empty, hence fieldInfos.hasVectors returns false.
> will post a patch shortly.
