well yes your information is really helpful.I did find a topics and qrels file that come in /src/lia/benchmark in the LIA2 sample code. and the result did change slightly.but the precision and recall value is still zero. I did also happen to use QueryDriver as you're suggesting and the result is also the same as precision and recall is still zero. I really need the value of precision and recall to be anything but zero I also put this question in stackoverflow so you can check this link if you wanted to know more of my problem. http://t.co/t0hat0T so any further advice would be helpful though :-) -- http://jacobian.web.id --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
