If you find the JIRA # I'll see if we can't have a go at fixing it...

Since I can't use .match() I want to run expression against the database to
see if "this" matches the filter, but I don't want *lots* of returned
results where I need to check that "this" is in the list of objects.
If I could create an expression that filtered out all objects that was not
"this", then I would know that the object matched the expression if
a single record was returned.
