getting rid of 'empty' segments
if index is updated continuously then in some moment we will have one or more segments in index that have all documents deleted. As long as deleting happens in IndexReader can we delete such 'empty' segments in IndexReader.close()? -- regards, Volodymyr Bychkoviak
Re: getting rid of 'empty' segments
Optimizing is also solution but described approach can save a lot of space and time needed to completely rewrite huge index...

Re: getting rid of 'empty' segments
followup:
in SegmentReader.doCommit()
we can add check
if (deletedDocs.count()==deletedDocs.size()) {
//delete this segment
}
deleting segment can be done by code that is contained in
IndexWriter.deleteSegments(Vector segments) method.
Any thoughts about some refactoring to allow SegmentReader use this code?
Does it all make sense?
