This is related to an earlier posting (http://www.nabble.com/Document-boost-not-as-expected...-tf3476653.html). I am trying to determine a ranking for users that is between 1 and 1.5. Because of the way the encoding norm is stored, if index time boosting is done, everyone gets a score of 1, 1.25 or 1.5. Is there any way to get around this so that all the values can be retrieved as is (e.g. 1.22, 1.35 etc).
One option is to override the norm encoding in Similarity, and re-index. You'd still be limited to 256 values. You could also store doc boosts that span a wider dynamic variance (1 to 15 rather than 1 to 1.5, say), then compensate by applying a query-time boost of 0.1. -Mike
