get-instances-by-value is a low level primitive, so it operates only on a
single index.
I have a triple-store / ontology hack in my contrib directory. I haven't
looked at it in a couple of years but you may find it useful.
elephant-1.0/src/contrib/eslick/triples.lisp
There is also a query system in the works which would do the two index scans
and merge for you, but I wouldn't hold out for it; it's low on my priority list
these days.
