I'm trying to reduce the memory requirement of my application that has ~40 indexed fields. Would I be wasting my time omitting norms in this application?
What would I lose by omitting norms? The ability to boost individual fields as they are added to the index? Anything else? [I want to check that I can get away without knowing about norms :-)] -----Original Message----- From: Yonik Seeley [mailto:[EMAIL PROTECTED] Sent: 10 July 2006 18:01 To: java-user@lucene.apache.org Subject: Re: What are norms? Norms are per indexed-field. For every document it's the product of the lengthNorm and the index-time boost. It's really more of an implementation detail that you shouldn't need to know about unless you have a lot of indexed fields and want to omit them for memory reasons. See DefaultSimilarity javadoc for lengthNorm... it's what makes hits on shorter fields score higher. -Yonik http://incubator.apache.org/solr Solr, the open-source Lucene search server
