: I see, well if you say the norm isn't a problem for my case, I will just : disable the coord factor by initializing BooleanQuery(true); and I should be : done.
querynorm hsouldn't be a problem (since your booleanqueries all have hte same structure, and odn't use query boosts ... i assume) but field norm might be; i also don't see anything mentioned so far in this thread that describes how you'll work arround the tf and idf values being theretically unbounded (unless your docs are all of identical length) ultimatley, attempts at comparing scores across different searches all come down to normalizing (either explicitly or implicitly) and normalizing requires that you have a "max possible score" you can normalize relative to -- not just a "max score for the index", but a max score in the scope of all theretical documents (because otherwise the comparison isn't fair given an arbitrary corpus) with the default similarity, you can't really define a "max possible score" for a given query because tf and idf are not bounded functions. There have been a few nice discussions about this general concept over the years, here's the first once i found doing a quick search... http://www.gossamer-threads.com/lists/lucene/java-user/61075 -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
