Subject Re: IndexWriter.getReader.getVersion behavior
Date Fri, 26 Feb 2010 20:11:30 GMT
Note that it's a BG merge (not commit)...

You can use the new (as of 2.9 I think) IndexWriter.waitForMerges API?
 If you call that, then call .getReader().getVersion(), then close &
open the writer, I think (but you better test to be sure!) the next
.getReader().getVersion() should always match.
