Searching for solutions, I have not got any results which talk about similar requirement... I

results are returned. Thanks in advance Chandrakant K. -- View this message in context: http://www.nabble.com/Terms-with-negative-boost-should-not-contribute-to-coord%28%29-tp24477758p24477758.html Sent from the Lucene - Java Users mailing list archive at Nabble.com
