The LIRE Solr integration uses a value source, which can then be used as
a sort function. However, if I want to implement both sorting by image
similarity *and* discarding docs with dissimilar images above some
custom threshold (while retaining proper facet counts), I would have to
do something like:
q=category:123&fq={!frange l=0.0 u=100.0 cache=false
cost=1000}lirefunc(cl, "WHATEVERFEATUREVECTOR")&sort=lirefunc(cl,
"WHATEVERFEATUREVECTOR")+asc
So unless I am mistaken, I would end up evaluating feature vectors
TWICE, which is what I'm trying to avoid, as I wrote in my original post.
Cheers, Patrick
