I have just pushed a change which does the following:

1. It makes a link like [[Find this text]] only match if there is an
   exact headline like this.  The fuzzy text search that used to
   result from such a link at least I never use in Org files

2. If there is no match, it offers to create this headline.

Let me know if this works for you.  Also: does this break
things for anyone else?
