Abstract: A method and system for improving text searching is disclosed. The method and system provides a network of document relationship and utilizes the network of document relationships to identify the region of documents that can be used to satisfy a user's request. In a preferred embodiment, the text searching method in accordance with the present invention augments a conventional text search by using information on document relationships and metadata. The text searching method and system improves upon conventional text search techniques by incorporating relationship metadata to define regions to search within. In the present invention the definition of a region is not limited to just categories as it includes neighborhoods around individual documents and sets which have been user defined.

Abstract: A voltage surge suppression system for the protection of electronic equipment from damage from voltage surges and voltage transients has at least one metal oxide varistor electrically connected to a primary power source; a transformer; at least one second metal oxide varistor electronically connected between said transmission interceptor and a power circuit board; and a circuit opener electronically connected between the a transformer and power circuit board; wherein the a transformer is connected between the primary power source and second metal oxide varistor. The circuit opener is a resettable breaker for protecting the transformer from surges greater than the rated value of the second metal oxide varistor by opening in order to close off current flow.
