[elephant-devel] including multiple slot-names and their values in the API get-instances-by-value

[Ian Eslick]

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.

Regards,
Ian
