A search engine is for accessing indexed information sources with automatic registration of information sources requiring registration and without requiring the submission of user identification data by the user each time that access to a registration information source is desired. The search engine obtains user information data from a user from a single submission to provide automatic access to all indexed registration information sources, as may be required by the search query and the selections of respective classification categories selected for narrowing the search. A user web page at the search engine stores search queries and corresponding search results. The search engine performs automatic search updating and notifies a user of the update based on user requests.
