Thanks very much for the response, Erick. I think one of my co-workers tried to use it and seemed to think it didn't meet our needs but I'll give it a shot.
In the meantime, I'm curious to see if anyone else has modified BooleanQuery to modify how calculates the score. Is the only way to do that to make a copy of the classes? -----Original Message----- From: Erick Erickson [mailto:erickerick...@gmail.com] Sent: Tuesday, December 07, 2010 4:57 AM To: java-user@lucene.apache.org Subject: Re: Help Overriding behavior in BooleanQuery scorer I haven't a clue about the package protected thing, but you may not need to go there.
