Subject [Fwd: Re: Lucene 3.0 Search Performance Stats]
Date Mon, 22 Mar 2010 13:12:14 GMT



Hi ,


I am also using range based searches for dates .I am converting time  to
utc based seconds format and storing them to indexes. and then running
range queries


Is there something needed to make it more efficient.

Thanks,
Suman
