With the navigation search bar, if I search for “green cookies” for example, and then a moment later decide to search again for something else, I would expect a new search bar with no previous phrase in it, but instead i get the search bar with “green cookies” phrase already in it. So now I have to delete the phrase before typing, or what I type will just get tacked onto the beginning of “green cookies”. How can I make it function so that successive searches will start with a blank slate instead of being prefilled with the previous search term?
