Hoss Man commented on SOLR-349:
-------------------------------
the idea that funcname(a,b,c,d,e,f,g,....) maps to a*b + 1*c + d*e + f*g + ...
seems a little weird, even weirder that funcname is "linear" which in theory
only has 3 inputs.
wouldn't a new "sum(....)" function make more sense? ...
sum(linear(a,2,3), linear(b,4,0), linear(c,5,0))
(the key being that "sum" takes in a list of other ValueSources, while linear
still takes only 1 and some constants)
we'd also need a "mult" function right?
