Context information, obtained by one programmable search engine and relating to a user, is stored in a central shared repository so that it can be used by other programmable search engines, in order to provide more effective targeted search results for the user in the future. Information obtained from other sources, including from the user him- or herself, can also be stored in the repository for future use. A programmable search engine consults the shared repository when processing queries and/or results, so as to incorporate previously stored context information concerning the user.
