You have to use the appropriate tool to do a recursive search
For grep it's the -r option.

Search the word "defun" in all my elisp dirs and subdirs:
,----
| (diredp-do-grep "grep -nHr -e defun   /home/thierry/elisp/icicles")
`----

==> 2 mn 11

But you can use more convenient tool like traverselisp.el.

M-x traverse-deep-rfind RET /home/thierry/elisp/icicles RET defun RET .el

==> 37 s

Faster but traverse is set to ignore all .hg, .svn etc...
You can set that as you want. (for files also)
Here it search only on .el files.

traverselisp is on emacswiki at:

http://www.emacswiki.org/cgi-bin/emacs/traverselisp.el
or
hg clone http://freehg.org/u/thiedlecques/traverselisp/
