Abstract: Systems and methods for searching multiple resources via a communications network, such as the Internet, are disclosed. The systems use a client-server approach in which search clients formulate search requests for a plurality of resources in a generalized format. The search requests are sent to a server, and specific uniform resource locators (URLs) for the desired resources and search terms are returned to the clients. The clients display the search results grouped by category and by resource, for example, with two sets of tabs. Each set of results is rendered using a browser engine, and the set is generally presented in its entirety. The server may define the resources available to the clients for search, and may also provide promotional information with the search results. Particular resources and features may be made available to particular groups and users.
