in emacs -Q, with my org files, (org-link-search "*test") will hang in
org 9maint, but not in org 8.  debug on quit produces this re.

  re-search-forward("^\\*+ +.*\\(?:COMMENT[ 	]+\\)?\\(?:\\(?:[

I committed a simplification of `org-link-search' so it no longer
produces this kind of regexp.

Anyway, please report if you encounter the freeze whenever you get the
chance to test the fix.

file links don't hang now, thanks.

however, if the header to be searched consists of only a link, it
fails to find the link.  perhaps it needs regexp-quote.

I'm not sure to understand. Is the example above self-contained, i.e.,
is the link supposed to match the same headline?

If so, it cannot work since you are not looking for the exact title. You
may want to use a custom-id.

header a has a link on it.

  * [...]

header b is created by capture and points to header a.

  * [...]

this goes to the file but fails to find header a.

Could you fill in the dots and give the capture template you're using?

Thank you.

Currently Org has no satisfactory way to handle square brackets within
links' path or description. Percent-escaping (e.g., "%5B")is not one.

I suggest to use a custom ID for the time being.

If you think there is another bug, please start another thread and
provide as much information as you can.

hmm.  seems links are not, or at least not yet, a complete syntactic solution.

> I suggest to use a custom ID for the time being.

i do but i don't want to clutter org with properties drawers.  i
already have a lot of ids and when org needs to search them it can
take some time.

basically i use non-id links for ephemeral tasks or to point to
ephemeral tasks.  i know i won't change the headers, but i want the
links there.

nah, making capture not follow is sufficient.  i don't know the
optimal solution.
