    Description

      We make use the docIDs in lucene. I need a way to compact the docIDs in segments
      to remove the "holes" created from doing deletes. The only way to do this is by
      calling IndexWriter.optimize(). This is a very heavy call, for the cases where
      the index is large but with very small number of deleted docs, calling optimize
      is not practical.

      I need a new method: expungeDeleted(), which finds all the segments that have
      delete documents and merge only those segments.

      I have implemented this method and have discussed with Otis about submitting a
      patch. I don't see where I can attached the patch. I will do according to the
      patch guidleine and email the lucene mailing list.

      Thanks

      -John
