Subject Re: Solr query with more than one field

: Because the value of the function will be treated as a relevance value

: filtered out.

I don't believe that's true? ... IIRC 'fq' doesn't care what the scores 
are as long as the query is a "match" and a 'func' query will match as 
long as the function says it matches ... something like sub() should be a 
match as long sa both fields exist in the document.

Pretty sure the simplest version of what you want is 
'fq={!func}gt(value,cost)' .. of if you need more complex functions/rules 
you can use the 'frange' QParser to only match documents where the result 
of an equation is in a specific range of values...
