> I've noticed IndexWriter's ctor commits a first commit (empty one) if a fresh
> Directory is passed, w/ OpenMode.CREATE or CREATE_OR_APPEND. This seems
> unnecessarily, and kind of brings back an autoCommit mode, in a strange way
> ... why do we need that commit? Do we really expect people to open an
> IndexReader on an empty Directory which they just passed to an IW w/
> create=true? If they want, they can simply call commit() right away on the IW
> they created.
> I ran into this when writing a test which committed N times, then compared
> the number of commits (via IndexReader.listCommits) and was surprised to see
> N+1 commits.
> Tried to change doCommit to false in IW ctor, but it got IndexFileDeleter
> jumping on me .. so the change might not be that simple. But I think it's
> manageable, so I'll try to attack it (and IFD specifically !) back :).
