Hm, I think not without changes to the core. It looks like I forgot to add those arguments to the filters.
Anyways, I will definitely fix that in the upcoming release, but until then, you can fix that by replacing one of the plugin files:
1. Open up the wp-content/plugins/ajax-search-pro/includes/classes/search/class-asp-search-indextable.php file on your server.
2. Replace it’s contents with this
3. Save
Now you should be able to use the same arguments as on the regular engine (query, $args, $phrase, $phrase_array)
