Subject [jira] [Created] (LUCENE-3403) Term vectors missing after addIndexes + optimize
Date Fri, 26 Aug 2011 06:37:29 GMT
Term vectors missing after addIndexes + optimize

                 Key: LUCENE-3403
             Project: Lucene - Java
          Issue Type: Bug
          Components: core/index
    Affects Versions: 3.3
            Reporter: Shai Erera
            Assignee: Shai Erera
            Priority: Blocker
             Fix For: 3.4, 4.0

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.
