@NickWeir this has not been asked by any user in France, and we have lots of things asked by our user which are higher priority for us (like subscriptions v2.0), so I don’t think we will be able to cobudget on that one 
From our experience in Frace with the products category fitler + search box you can cover most of the searches, but I understand that in some big hubs with thousands of products those search tools might not be efficient enough… But I’m wondering if the solution is to use such meta tags and enable search in those tags, or improve the menu system and enable sub menus for instance… that’s a request we have by some users who would like to be able to organize their products in their shop in a more flexible way… but probably another discussion
