A method is performed at a server system having one or more processors and memory. The server receives a search query from a user and identifies a list of search results associated with the search query. Each search result has an initial position in the list. The server identifies a set of user-preferred search results that comprises search results in a search history of the user. Each of the user-preferred search results has been previously selected by the user for at least a predefined minimum number of times. The server identifies in the list of search results, one or more search results that are associated with at least one of the user-preferred search results and reorders the list of search results by moving each of the identified search results from its initial position by a non-zero offset. The server then provides the reordered list of search results to the user.
