RE: "contains" must be optional

I agree: support for contains must be optional.

I vote for the error response (as opposed to treating it as unknown). This
just strikes me as simpler. Also, a query engine can always always advertise
support to the seach arbiter for the contains operator and then implement it
as "unknown". So, by using an error response we actually still allow both
behaviors.

Thanks,
