I would like to know is possible that modify the results page in the action when pressing the button. Is possible that?:
a) show (some text): write title or custom fields values
b) hide the date?
c) hide the READ MORE button?
I was copy the PHP files from /wp-content/plugins/ajax-search-pro/includes/views/results into the new directory to /my-theme/asp, and modify some code, but nothing happened.
The results page is fully controlled by the theme you are using (or page builder). Unfortunately the plugin cannot affect it’s appearance, you will have to ask the theme author, or look for the settings there.
