[rules-users] Matching strings in two arrays

[Wolfgang Laun]

You could define a new operator (similar to "contains" or "memberOf") that
tests whether a field - a set of values - is a subset of a another set of
values.

See my home page for a full recipe:  http://members.inode.at/w.laun/

The code given there is for both sides being java.util.Collection. Handling
of
arrays could be added. But you should also consider providing the sets for
the rules as static auxiliary facts.
