Systems and methods for promoting personalized search results based on personal information

An information server identifies a list of search results associated with a search query from a user. Each search result has an initial position in the list. The information server then identifies a user profile associated with the user. In some embodiments, the user profile includes a set of user-preferred search results that is determined at least in part from the user's search history and one or more supplemental search results that are deemed similar to at least one of the user-preferred search results. Among the list of search results, the information server identifies one or more search results that are associated with the supplemental search results. Finally, the information server reorders the list of search results by moving each of the identified search results from its initial position by an offset and then provides the reordered list of search results to the user.
