How to Redirect WordPress Search to WooCommerce Shop Filter by Product Title or SKU

In the Bricks Facebook group, a user asks:

I'm a bit lost with the product search on my e-commerce site. I have a search bar in my header and I want to display the product archive page with only the results if I type the product name or its SKU. Can anyone help me? I don't quite understand.

One way to do this is by

1. using a Filter - Search element on the Shop page
2. configuring it to search for product titles and SKUs
3. adding a custom search box that sends the search term to the Shop page with the correct URL parameter. Ex.:example.com/shop/?_product=V-Neck+T-Shirtorexample.com/shop/?_product=woo-vneck-tee
4. adding custom code that redirects WC product title and SKU search terms to the Shop page
5. additionally, removing products from the default WP search results

This Pro tutorial provides the details of how the above can be done to essentially redirect users to the Shop page with filtered results if the searched term matches a WC product title or SKU. And, if it does n't, to the default WP search results.

Step 2

Add the following in child theme's functions.php (w/o the opening PHP tag) or a code snippets plugin:
