I'm not sure I follow your logic now. If one can express the popularity as a value between 0.0 and 1.0, why can't one use that, together with a weight (indicating how much the popularity should influence the score, in general) and add that to the text relevance score? And how, exactly, would I achieve that using any multiplicative formula? The logic of the weight, in this case, is that I want to be able to tweak how much influence the popularity has on the final score (and thus the sort order of the documents), where a weight of 0.0 would have the same effect as if the popularity wasn't included in the boost logic at all, and a high enough weight would have the same effect as if one sorted the documents solely on popularity. /Jimi
