When you perform a search on Google from a registered account, a search history is created detailing the search terms or phrases you entered. These search terms are offered as suggestions when you begin typing similar terms in the Google search bar. Although helpful for rediscovering past searches, this potentially offers others an opportunity to see your search patterns. To protect your privacy, you can delete one or all of your search terms.
