Hi Trevor,
The endgoal is to delete the posts but I’ve tried both wp_delete_post (with forced delete) and wp_trash_post followed by wp_delete_post to remove the posts.

In both cases the posts are still in S&F caching tables after the post is deleted.

Yes, I am indeed doing this with code.
I’ve tried using do_action(‘search_filter_update_post_cache’, $post_id).

However if I call this after wp_trash_post the post is still in the caching tables.
If I call the action after wp_delete_post the post is removed from the caching tables but it causes several php-errors:

Hi Trevor,

Is there any news on this?
