Description

When trying to manage an auxiliary index to lucene, IndexWriter.java 3.5.0 does not provide a proper hook. Such a hook (see attached proposed patch) permits us to manage an outside index where we get 1 of our segments in parallel to the lucene segments, and we can keep the same docid offsets within the segment.

We are attaching a suggested patch that provides an override-able method. We would like this accepted for 3.5+ if possible. Thanks.
