How do I delete query suggestions from Google search bar?
Go to the Google “Preferences” page. (See “Resources.”) Scroll down to the “Query Suggestions” section. Click the “Do not provide query suggestions in the search box” radio button. The green dot will move from the “Provide query suggestions in the search box” radio button, to the “Do not provide query suggestions in the search box” radio button, indicating that your preferences setting has changed. Click the “Save Preferences” button at the bottom of the Preferences web page.
