Search form: no found message

Hi there,

Configuration :
Elementor
woocommerce

I created and archive template for my search results using the products widget.

In my header I added the search form widget.

When products are found, the message of results count is ok.
But when nothing is returned, there is no message : “no products found” displayed.

Is this a bug, or how can I fix this with maybe with a code snippet.

Thank for your help.

Cheers.

Catherine.
