Hi,
Do you mean the results on the results page?
I’m afraid that is only possible by editing the theme. The WooCommerce results page will automatically remove anything that is a product. The regular results page however may not display the add to cart button. Unfortunately the plugin can not affect that, it is purely rendered by the theme you are using.
Theoretically if everything were to be rendered on the regular results page (not the WooCommerce one), that should be custmomizable to display everything as you like – but that is definitely not an easy task.
