: So, this query does just what I want, but it's typically 3 times slower : than the edismax query without the functions:
that's because the scale() function is inhernetly slow (it has to compute the min & max value for every document in order to know how to scale them) what you are seeing is the price you have to pay to get that query with a "normalized" 0-1 value. (you might be able to save a little bit of time by eliminating that no-Op multiply by 1: "product(query($qq),1)" ... but i doubt you'll even notice much of a chnage given that scale function. : Is there any way to speed this up? Would writing a custom function query : that compiled all the function queries together be any faster? If you can find a faster implementation for scale() then by all means let us konw, and we can fold it back into Solr. -Hoss
