Sorry to jump into this thread, but are you saying that the facet count is
not # of result hits?
So if I have 1 document with field CAT that has 10 values and I do a query
that returns this 1 document with faceting, that the CAT facet count will
be 10 not 1? I don't seem to be seeing that behavior in my app (Solr 3.5).
Thanks.
