Also, if you don't like the tag solution, you could borrow something right from LIA... boost the documents that are "significant" products with 1.5 (or whatever higher then 1), and the support/ancillary products boot with .1
If there is nothing relavent in the "significant" products, at least you'll get some of these. After all they may search for "bolt" .... maybe they want an ancillary product. -----Original Message----- From: Mufaddal Khumri [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 21, 2006 12:06 PM To: java-user@lucene.apache.org Subject: Re: get results by relevance, limiting results and then sort the results by some criterion So yes, if the xth + 1 item happens to be a camera and if its price happens to be lower than the previous x cameras it wont be included in this view and that is exactly what we want.
