: We've had a couple of people ask for scores as percentages. If you really : want this, it should be just barely possible, though it would take some : coding. You calculate the maximum possible score, then report scores : normalized against that.
Right ... this idea has come up on the java-user list before, and was *linked* to from this wiki page... http://wiki.apache.org/lucene-java/ScoresAsPercentages ...but i just updated the wiki to elaborate on the concept and why i don't think it's a good idea. (nutshell: it still suffers from the problem of scores not being comparble between differerent queries (with differnet structures) and the percentage for queryA=>docX can change when docZ is are added or removed even docZ documents don't match the query at all. -Hoss
