Abstract:
An incremental search engine method, performed on a server computer system connected to a network, is disclosed. The method allows to provide incremental search results to a large number of users in a timely and efficient fashion, facilitating the discovery of new information on the Internet or in corporate intranets. Users submit queries, which are stored on the server computer system. Once a query has been submitted, it is automatically checked against any new or modified documents retrieved from the network by a difference crawler, and new matches are presented to the submitter of the query. In the case of modified documents, only the novel portion of the document is considered for determining the new matches. For
