IMHO it would be nice if Lucene's Similarity formula took the indexed-date of the document into account. Ideally as an optional setting, where the user can provide a date field as well.
Some of the other search engines do - for example Fast's Instream. It makes sense that as documents age over time, they are less important than the new ones. Is JIRA the mechanism where you can add "feature requests" for Lucene? -----Original Message----- From: Dominik Bruhn [mailto:[EMAIL PROTECTED] Sent: Sunday, December 30, 2007 4:38 AM To: java-user@lucene.apache.org Subject: Re: Prioiritze new documents Hy, a solution came into my mind: Every document gets boosted by a integer which I increment each time I add a new document to the index. So the newer documents should get a bigger boost than the older ones. I tried it out and ran into a problem: Although I set the Boost via doc.setBoost(value) for each document before writing it to the index it doesnt change anything. Even worse if I look at the index using Luke (Version 0.7.1) each document got a boost of 1 not of the value supplied. Who can help me?
