Similar products when empty results

Hello!

I hope You are well. Your plugin is great!
As we know, empty results are the most common reason for a customer to leave a store. I would like to know how can i put similar products to the customer search when they are empty. I would like to display them under the message ‘no products found’. If that is impossible, what’s the hook of this place? in the default woocommerce search engine it is ‘woocommerce_no_products_found’.

Best, Mateusz.
