Includes Product Custom Fields to WooCommerce Search Criteria
forget about the other plugin "Search By SKU".
this here is the only one which works for me! i have latest WP and WC versions.
you just save my life
It is not search by Custom Field.
It is search only in Custom Fields.
Works just like that out of the box when searching for custom fields. Good job.
This is exactly what I was looking for. Just activate it & any custom fields you have created for your woocommerce products will be searchable through your theme's default search. No need to adjust any settings.
