Better User Search is a must have plugin if you’re running WooCommerce. Without it, you’re stuck trying to remember every 
customer’s username.
Better User Search is used to improve the user search functionality in the admin/backend.
WordPress by default only allows you to search for users by username/nicename. Using Better User Search, you will be able 
to search by first name, last name, email address and any custom user meta field that already exists in the user meta table.
On top of that, there is an “OR” feature provided. Just include the word “or” (case-insensitive) in your search query 
and the plugin will search for any user that matches at least 1 of the search terms.
“OR” Search Example: 
Let’s find all WooCommerce customers in Texas or Florida. To do this, first make sure that <code>billing_state</code> and <code>shipping_state</code> 
are setup in the Better User Search settings. Now head to the Users page and type “TX or FL” into the search field.
It really is that simple! 
Special characters like quotes are escaped, problems with the query may appear when trying to search for other non-alphanumeric characters.

Enhance the default WordPress admin search by including custom fields (post meta) in search results. 
This plugin seamlessly extends the post listing (edit.php) search functionality, allowing administrators to quickly find content based on values stored in custom fields.
It works out of the box with no configuration required—just activate and start searching. 
Especially useful for sites that rely heavily on custom fields, such as those built with ACF or other meta-based data structures.
Lightweight, efficient, and fully integrated with the native WordPress admin experience.

WP-Admin Search Post Meta

Search WordPress admin posts by custom fields (post meta) directly from the default search.
