With point over the link here,
org-open-at-point jumps to the following line ("ham eggs"):
* spam ** spam [[ham%20eggs][ham eggs]] ** ham eggs
Here however (final line extended), the same action makes emacs prompt
No match - create this as a new heading? (y or n) in the minibuffer:
* spam ** spam [[ham%20eggs][ham eggs]] ** ham eggs spam
Is it possible to define links that do a substring search, so that the search would succeed in this case? It certainly is possible when linking to non-org mode files, and I would like to do the same for internal links.
