I got this reply from theme author. How can I add ‘&post_type=auto-listing’ to my search parameter.
Hi,
This is AJ the theme author.
If we do a little test adding the post type at the end of your URL – https://www.wrecky.com.au/wrecking/?make=Audi&the_year=&s=&post_type=auto-listing – you can see the items display correctly. So it looks like your directly plugin does have the correct code needed to display the auto listings.
I wasn’t able to locate any search function on your site, but if you are adding a custom search element just be sure to also have the post type added in the search form so that it correctly displays the items.
And the most likely reason why the items don’t show up on the regular search results is probably because the plugin excludes them or you have enabled this option in the Customizer – https://a.cl.ly/d5uAe15Y
