Search Form Reset/Clear is Needed

[lbramirez]

Hi - At the bottom of this page is the search widget:
http://vitanica.com/all-products/productlist/

If you enter something such as "noexist", you will get a "not found" result, which is correct.

Now on the same page (without a page "refresh") if you enter something valid such as "iron", you still get "not found" which is NOT correct.

Can I do something to force a page/form reset so that if a user enters a valid term after a "not found" the form will correctly return the results?

Thank you, Laura
