Query logs are accessed to obtain queries, user information that specifies a user from which the query was received, a long with a selected result that was selected by the specified user who authored the query. This query log information is used to identify classes of users that looked for a similar result given a similar query. Those classes can then be used by a search engine in order to rank or provide search results to a user in response to a query input by the user.
