[]In WooCommerce, there are two kinds of search: the customer one (frontend) and the admin one (backend). We’ve already covered how to let customers search into custom field values on top of the default product title and description, so this time we’ll talk about the backend search.
[]Let’s say, as a WooCommerce store admin, that you’ve added a product custom field (e.g. “gtin“), and you want to make sure the backend search also returns products where “gtin” is equal to the search term. The snippet below will help you do that. Enjoy!
I’d like to search products by “ABC” as per the screenshot above, where “ABC” could also be present in some custom fields. The snippet below fixes that.

Where to add custom code?
[]You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files – if you need more guidance, please take a look at my guide “Should I Add Custom Code Via WP Editor, FTP or Code Snippets?” and my video tutorial “Where to Place WooCommerce Customization?”
Does this snippet (still) work?
Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.[]If you think this code saved you time & money, feel free to join 17,000+ WooCommerce Weekly subscribers for blog post updates and 250+ Business Bloomer supporters for 365 days of WooCommerce benefits.
