Hi @youssefrigale!
By default, your product search results page should display products. To find out why this is not the case, I would like to receive a bit more details from you. Do you use any page builder? Are you using a theme that allows you to create your own search results page? Does the search results page have the following parameters in the URL: /s=tests&post_type=product&dgwt_wcas=1
? Maybe there is some redirection on the search results page?
Regards,
Kris
