Thanks for answering...
One last control question, I hope you can answer, before I buy your plugin:
In the default /components/com_search on Joomla 2.5, the file I copied to my template (the override file) named default_results.php,
was originally in this Joomla folder:
Does your plugin use the same file-structure as the original Joomla component?
If it does, then my guess is that I should be able to copy the same file from your component (default_results.php),
and place it in the folder below (with the com_search changed to match the name of your extension (to enable override and custom output of the search result on the fronted):
What do you think?
