Subject Re: How can we know if 2 lucene indexes are same?
Date Thu, 04 Sep 2008 09:08:44 GMT
No documents can added into index when the index is optimizing,  or
optimizing can't run durling documents adding to the index.
So, without other error, I think we can beleive the two index are indeed the
same.
