It doesn't look like there were any replies to this while i've been away, so i just wanted to point out that this isn't really a practicle thing to do because the score's don't have any meaningfulll absolute value (ie: you can't compare the scores from one search with the scores of another). the first Hit will allways have a score of "1" and the score of the other hits will be normalized against the first one.
I've added this to the FAQ as "Can I filter by score?" http://wiki.apache.org/jakarta-lucene/LuceneFAQ http://wiki.apache.org/jakarta-lucene/LuceneFAQ#head-912c1f237bb00259185353182948e5935f0c2f03 : Date: Sat, 13 Aug 2005 16:49:12 -0700 : From: Chris Fraschetti <[EMAIL PROTECTED]> : Reply-To: java-user@lucene.apache.org : To: java-user@lucene.apache.org : Subject: post-normalization score filter : : I've seen a few posts which reference using a HitCollector to help : filter the returned document's scores.. but are there any : implementations out there that perform this filter of results by score : after they've already been normalized, short of walking the hits : array.... If i was to walk hits until i reach my threshold, just : checking the hits.score() ... what am I looking performance wise, are : the scores all calculated at this point and I'm simply accessing them : or are they normalized on the fly? : : Obviously I can trim my results a bit for results that score a million : documents only allow the first few thousand as results, but even in : the case of where I might get two thousand results, the lower end : results have such minimal scores in comparison to the earlier that it : seems unintuitive for them to be accessible. : : thanks as always! : : -- : ___________________________________________________ : Chris Fraschetti : e [EMAIL PROTECTED] : : --------------------------------------------------------------------- : To unsubscribe, e-mail: [EMAIL PROTECTED] : For additional commands, e-mail: [EMAIL PROTECTED] : -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
