Is it possible to add ACF fields to the admin search? I specifically do not want the fields searchable on the front end.
You need to create a “pre_get_posts” filter that runs in the admin for your post type, and add a lot of other filters, see this https://wordpress.stackexchange.com/questions/99849/search-that-will-look-in-custom-field-post-title-and-post-content. It is quite a complex procedure.
Hmm, yes – that’s not straight-forward is it.
I’ve identified this plugin as a potential solution so I’m going to investigate that first.
Thanks for your help.
