keyboard regexp shortcuts

Very often, I do a regex search (M-C-s) of \_<foo\_> because I don't want to find bad_foo_dog.

Typing the \ _ < and \ _ > is tedious.  Can someone suggest a way to make that easier?

Thank you,
Perry

Here's what I use:

(defun my-isearch-word ()
   "Surround current input with word/symbol delimiters and turn on regexp matching if necessary."
   (interactive)
   (unless isearch-regexp
     (isearch-toggle-regexp))
   (setq isearch-string (concat "\\_<" isearch-string "\\_>")
         isearch-message (mapconcat 'isearch-text-char-description isearch-string ""))
   (isearch-search-and-update))

(define-key isearch-mode-map (kbd "M-w") 'my-isearch-word)

In development version of Emacs, there is a better way.
