Thanks for your response.
I don't think contains will work in this case. I need to match if a collection contains one, and only one, of another collection. So " ('a','b','c') contains one of ('a','b','e') " should not match, where "('a','b','c') contains ('a','2','3')" should match.

You have the answer in your example, reserved word "contains" will give you that information.
