I could be wrong but that (user input validation) should be done prior to RegExp construction.

That was it, it works now, thanks.  Funny, I didn't notice that, I had
it in my code before, but somewhere along the line of messing with
things, it just switched back over to .toString() and I hadn't noticed.
Thanks everyone!
One more question if I may - how can I exclude certain things like blank
spaces?  I mean, I could check the textfield, but it would seem there is
an easier way.  If I put a blank space (or nothing for that matter) in
the input text field and search for that, it returns all nodes.  I could
check the input text field, but I'd rather do it with a regular
expression (both for elegance and to learn).  The help docs are skimpy,
so excuse so many questions here.  It's also such a huge subject, it's
very hard to Google exactly what you need.
