Try this one: [[elisp:(occur "foo")]]

"occur" is a standard emacs feature which lists all lines matching a
given regexp.

If you're going to use this, I'd recommend setting
org-confirm-elisp-link-function to 'with-y-or-n for less annoyance while
still being warned you are about to follow a link that can execute
arbitrary code.

You can go back to where you came from using C-c &:

| C-c & runs the command org-mark-ring-goto, which is an interactive
| Lisp function in `org.el'.
|
| It is bound to C-c &.
|
| (org-mark-ring-goto &optional n)
|
| Jump to the previous position in the mark ring.
| With prefix arg n, jump back that many stored positions.  When
| called several times in succession, walk through the entire ring.
| Org-mode commands jumping to a different position in the current file,
| or to another Org-mode file, automatically push the old position
| onto the ring.

I don't know about refolding the target headline.
