I currently use the following hook to achieve the level of detail I
like from a sparse tree:
(add-hook 'org-occur-hook
(lambda ()
(goto-char (point-max))
(while
(re-search-backward regexp nil t)
(show-subtree)
(org-cycle)
(org-cycle))))
I combine this hook with
(setq org-show-following-heading nil)
(setq org-show-entry-below t)
This works great unless regexp is within a fontified org-link. Then
Emacs hangs and I get the OS X spinning beach-ball.
There is a very easy workaround as re-search-backward has no problem
with an org-link if font-locking is turned off for the buffer:
(add-hook 'org-occur-hook
(lambda ()
(goto-char (point-max))
(font-lock-mode)
(while
(re-search-backward regexp nil t)
(show-subtree)
(org-cycle)
(org-cycle))
(font-lock-mode)))
Practically, I'm content with my solution, but I thought I'd mention
it should the bug lie within the org-link code and bite anyone else in
other situations.
OS X 10.5.6, Emacs 23.0.60.1 (NS), Org-mode 6.18c
Best wishes,

Hi Christopher,
turning font-lock off and on does seem to help, but it is a pretty big
cannon.
The reason hy your hook runs into problem is: When the match is in
text marked by an "intangible" property (like the link part of a link
that
also has a description), then the command loop moves the cursor you of
this location. Apparently this happens here. A more direct solution
might
be to move to the beginning of the line before continuing the search,
like this:
(add-hook 'org-occur-hook
(lambda ()
(goto-char (point-max))
(while
(re-search-backward regexp nil t)
(show-subtree)
(org-cycle)
(org-cycle)
(beginning-of-line 1))))
Or even better:
(add-hook 'org-occur-hook
(lambda ()
(goto-char (point-max))
(while
(re-search-backward regexp nil t)
(org-back-to-heading) ;; in case match was deeper in entry
(show-subtree)
(org-cycle)
(org-cycle)
(beginning-of-line 1))))
