Text Entry Questions

Is there a way to add a "wildcard" to a text entry so that as long as part of the entry is correct, it will accept the answer regardless of the rest of the typed in answer?  For example, if I wanted a user to provide the answer, "Bob" and the responder answered "Bob Jones", I would like it to accept the answer.... obviously, I could add an acceptable response for that example, but if there are many acceptable responses, I don't want to have to try and think of all of them.

Thanks!
