Searching in custom fields

You can either choose to search all custom fields, or search and select which custom fields to search within.
Searching all custom fields
For selecting custom fields, first turn off the Search all custom fields? option, then enter the custom field name to the search field - then drag it to the right side of the option.
If the custom field name does not appear in the list (like some Advanced Custom Fields ACF fields after creation), that means it is not yet have been assigned a value. When you create your first post with the newly created fields, and assign a value to it, it will appear in the list.

By turning on the Search in terms? option, the search within taxonomy terms (for posts and post types) is enabled.

Post statuses and password protected posts

By default password protected published posts are returned. You can add post statuses to the list (comma separated!), as well as turn off displaying password protected posts.
