Yeah, one can build a form that submits to super search to do a title search only for users. The instructions could instruct you to use ' ' not '_' for such searches. I don't know if such a form would trigger the super search protection against constructing URLs that actually trigger a (potentially expensive) search so instead just load the form and require a subsequent button push.

A tiny bit of coding could overcome the "don't just do the search" protection and also replace '_' with ' ' automatically.
