Delete search history

You can delete your search history at any time. However, before you do so, remember that saving your search history can help you quickly find information you’ve searched for in the past or pages you visited earlier. For example, if you visited a site with a great pasta recipe but can’t remember what the site was called, you can look through your search history to find it.
