As you can see on the screencast at http://screencast.com/t/MW8sTCtQ,
when searching for the string "w3m" in the following Org file:

--8<---------------cut here---------------start------------->8---
To be tangled:

#+begin_src emacs-lisp
  ;; use `w3m' browser (if installed) to render mails in HTML
  (setq mm-text-html-renderer
        (cond ((executable-find "w3m") 'w3m)
              (t 'html2text)))          ; Emacs built-in
#+end_src
--8<---------------cut here---------------end--------------->8---

Isearch only finds 1 occurrence, while there are 3 such strings
(correctly reported by Anzu as well).

It seems that the fact that this is an Org file has an impact. Doing the
same search in a `.el' file did occur correctly.
