Oh, you meant "versus" not "verses".  OK.  I'll shut up now.

So, I started looking at isearch-yank-word-or-char and I was going to concoct isearch-yank-symbol-or-char and got stuck-- at least briefly.  Because not only is _ marked as symbol, -, +, /, *, etc are marked as symbol characters too.  So now, I'm confused...

If I have:  this  this_that  this-that

and search for \_<this\_> I hit the first and third this -- which is exactly what I want.  But how is it doing that since this_that and this-that are the same as far as looking at the syntax table entries?  They are both wwww_wwww.

I'd like to understand how the \_< and \_> constructs work so I can make my isearch-yank-symbol-or-char work in a consistent manner.

Thanks,
Perry
