Length normalization of the field. Full-text matches on shorter fields score higher because the match is seen as more specific. You loose that if you omit norms. That's typically OK for short fields like "title" anyway, and fields that aren't full-text (like dates, numbers, etc). -Yonik http://incubator.apache.org/solr Solr, the open-source Lucene search server --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
