That sounds like a good idea.  I don't have time to fully implement
this, but here's a code snippet that might help you get started.

(defun get-matched-list (regexp)
  "Return the name and destination of Wiki pages that match REGEXP."
  (let ((list nil))
    (dolist (file-and-destination (emacs-wiki-file-alist))
      (when (string-match regexp (car file-and-destination))
        (push file-and-destination list)))
    list))

To test this out, copy it to the *scratch* buffer and hit C-M-x (alt +
control + x).  Then bring up a Wiki page and hit M-: (alt + shift + :
or ;).  Type (get-matched-list "foo") and you will see a list of pages
that match "foo".

You might need to (require 'cl-macs), but I don't know for certain.

Your site looks quite nice, by the way.
