Abstract: Embodiments of the present invention enhance the search experience of a user by looking at the search history of one or more friends to provide search enhancements to the user. The search enhancements may also be based on information within a user's online social network. Search enhancements based on the user's online social network include identifying people within the user's social network that may have information relevant to a query, posts within the social network that are relevant to the query, and feed items. Examples of search enhancements include an annotation or graphic adjacent to a search result indicating the search result has been visited by one of the user's friends. In another aspect, alternative queries from the friends' search history may be suggested to the user during the search session.
