I haven't completely understood what you're trying to do, but I have a
few points.
- I don't see any definition of an operator class, just the family,
which doesn't seem to make any sense to me.
- Does it work if you replace the use of the operator with the
equivalent function call (contains)?
- Check for differences in the explain output, that should reveal any
implicit casts that may be getting in your way.
Hope this helps,
