As Erik described, it is provided by Emacs, not Wanderlust.
Wanderlust does not suppose that it is used with Wanderlust.

Actually grep searching is not useful especially in searching
non-ascii characters.  Because such characters are encoded in various
coding system and content transfer encoding (such as quoted printable
and base64).  So, we recommend you to use 'V' (wl-summary-virtual) or
'?' (wl-summary-pick) in Summary buffer.


If you really need to grep in your localdir directory, try below and
run "Tools"/"Search Files (grep)" from Summary buffer.

(defun wl-summary-cd (&optional f)
  (let* ((folder (or f wl-summary-buffer-elmo-folder))
	 (type (elmo-folder-type-internal folder))
	 (target
	  (cond
	   ((eq type 'localdir)
	    (elmo-localdir-folder-directory-internal folder))
	   ((eq type 'pipe)
	    (wl-summary-cd (elmo-pipe-folder-dst-internal folder)))
	   ((eq type 'filter)
	    (wl-summary-cd (elmo-filter-folder-target-internal folder))))))
    (when target
      (cd target))))
(eval-after-load "wl-summary"
  '(add-hook 'wl-summary-prepared-hook 'wl-summary-cd))
