Howdy Org-folks,

Something that I've found myself wishing for time and time again is to
be able to follow the link to a file and immediately pop into a set of
M-x occur results given some search term for that file.  That way I
could link to an overview of a file's class/function definitions, or
config stanzas, or other useful things.  Given that we can create
links to arbitrary elisp, I am sure that this can be done in
principle, but if there's a quick recipe that someone has come up
with, I'd love to hear about it!

That seems like a fun exercise. so:

#+BEGIN_SRC elisp
  (defun org-occur-open (uri)
    "Visit the file specified by URI, and run `occur' on the fragment
  \(anything after '#') in the uri."
    (let ((list (split-string uri "#")))
               (org-open-file (car list) t)
               (occur (mapconcat 'identity (cdr list) "#"))))
  (org-add-link-type "occur" 'org-occur-open)
#+END_SRC

and you can use a link like:

occur:m/file.txt#regex
