Can This [ boost the Full WEBSITE ] be achieved in Lucene's search based on searchword If So Please Explain /examples ???. with regards karthik -----Original Message----- From: Chuck Williams [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 11, 2005 2:00 PM To: Lucene Users List; [EMAIL PROTECTED] Subject: RE: QUERYPARSIN & BOOSTING Karthik, I don't think the boost in your example does much since you are using an AND query, i.e. all hits will have to contain both vendor:nike and contents:shoes. If you used an OR, then the boost would put nike products above (non-nike) shoes, unless there was some other factor that causes score of contents:shoes to be 10x greater than that of vendor:nike. It's a good idea to look at the results of explain() when analyzing what's happening with scoring, tuning your boosts and your Similarity.
