Hi!
Thanks for your kind words!
I think you are looking for the results templating knowledge base article. There are basically template files for results, including the “No results” template. You are looking for the ajax-search-pro/includes/views/reuslts/no-results.php file. That file is parsed when there are no results at all. You can ad anything you want to that.
If I understand correctly you want to display the page related to the term instead of the term. In that case use the Search in terms? option on the General Options -> Sources panel: http://i.imgur.com/TN37T5b.png
