Filter results based on custom scoring and _val_

[jimtronic <ji...@gmail.com>]

I'm using solr function queries to generate my own custom score. I achieve
this using something along these lines:

q=_val_:"my_custom_function()"
This populates the score field as expected, but it also includes documents
that score 0. I need a way to filter the results so that scores below zero
are not included.

I realize that I'm using score in a non-standard way and that normally the
score that lucene/solr produce is not absolute. However, producing my own
score works really well for my needs.

I've tried using {!frange l=0} but this causes the score for all documents
to be "1.0".

I've found that I can do the following:

q=*:*&fl=foo:my_custom_function()&fq={!frange l=1}my_custom_function() 

This puts my custom score into foo, but it requires me to list all the logic
twice. Sometimes my logic is very long.
