I usually do C-s (C-w)+ while searching for symbols.
This is what I cooked up:
(define-key isearch-mode-map "\C-_" 'isearch-yank-symbol)
(defun isearch-yank-symbol ()
(interactive)
(isearch-yank-internal (lambda ()
(require 'thingatpt)
(forward-symbol 1) (point))))
I chose '_' (underscore) as it stands for symbols in much the same way
as 'w' stands for word.
Searching for symbols is something that I do often and I find it
convenient if some such functionality comes by default with emacs.
