Subject Reduce index size without reopening IndexWriter
Date Mon, 11 Jul 2016 11:45:56 GMT
I use Lucene 6.1.0 (no solr) with NRT search. At runtime, my index seems 
to grow a lot.

I think that for each commit, a new copy of the index is made. This 
makes sense as an old searcher could be using the previous version. 
However, the old copies don't seem to be erased until I close and reopen 
the Index Writer.

I've tried calling IndexWriter.deleteUnusedFiles after each commit, but 
didn't help.

Is there any way to free space without closing the IndexWriter?
