Sorry for the delay on our end. We didn’t get notified about this ticket.
At the moment, the plugin supports standard posts, pages, and WooCommerce products. Custom post types and custom taxonomies aren’t included yet, but it’s something we’re open to adding.
If you don’t mind sharing, how are you planning to use custom post types or taxonomies with search? That context would help us decide the best way to approach it.
You shouldn’t remove it as it’s there for legal compliance, but you can update the position of it by using a custom template. If the policy link is incorrect it pulls from WordPress so you can update it in wp-admin under Settings -> Privacy Policy. If you remove it from there it also will not show.
