The noresults alias

You can now create a special alias called noresults.

If user hits enter when no results are shown, this alias will be triggered.

It can be useful if you want to do something like launch what they type directly (as if it was on path), or invoke another search program, etc.  Just use $$1 in the results.

Important: you need to set the regular expression pattern to:

^noresults (.*)$
