If you fill in all the boxes on the right of the image, and then click "add to basket", it takes you back to the same results page you saw before - which still says "0 results". There now should be a big green headline near the top saying "added to basket", and a new menu item at the top of the page for "my basket(1)". That happens even if you are not logged in, though you do need to be logged into an account to complete and pay for the order.
