I have a custom post type books and have many meta boxes for it…etc But in the backend, I am not able to search anything.
For example I try to search the custom post type id in the search field, it comes back with no results.
How can I add different search items into the search query?
Lol, i was just having the same problem 😛
Well, this plugin is working for me: Search Everything -> https://github.com/sproutventure/search-everything-wordpress-plugin/ or in wordpress plugin page, by name search everything
