Check out the new Explanation API in the latest CVS sources. It permits one to get a detailed explanation of how a query was scored against a document. Note that these explanations are designed for user perusal, not for further computation, and are as expensive to construct as re-running the query, but it sounds like that fits your needs.
Wow, that was fast... :-) Yes, it seems this is the functionality I'm looking for. Do you think it would be possible/feasible to modify the searching classes so that they create Explanations at the same time I'm running the query? Should I expect a similar cost for that as creating Explanations separately?
BTW: I tried to contact you regarding some help in a commercial project. Is <[EMAIL PROTECTED]> the right way to do it?
Thanks!

Hello,
Is there any simple way to get the information from the search results on which of the query terms contributed the most to the document's score? I'm working on an application which could use this sort of information to give a hint to the user why particular document scores the way it does against particular query...
Any suggestions?
