The enhancement into search suggestion allows suggesting the previously searched terms to customers (shoppers) if the same browser is used.
When a customer (shopper) searches any terms on the web store, that term gets saved in the browser if the results for the term were available.
When any customer (shopper) using the same browser clicks in the empty search input box again, the application displays the last 10 searched terms with the most recently searched term at the top. When any term is selected/clicked, it gets added in the search input box and searched, redirecting the customer (shopper) to the Search Results page.
When a user clicks on the autosuggestion and searches for any of the products it opens a PDP (Product Details Page).
