Subject Re: TermQuery - ExactMatching, Lucene 3.1.0 vs. 3.3.0, special character behavior
Date Mon, 18 Jul 2011 08:08:42 GMT
I'm not sure what you are getting at.  A search using 3.1.0 and 3.3.0
returns the same docs with identical scores, except that one gives
them in order A,B and the other in order B,A?  What search method are
you using?  Does it guarantee anything about the order of returning
docs with identical scores?
