SYSTEM AND METHOD FOR SEARCHING DOCUMENT USING SIGNATURE CACHE OF DOCUMENT

摘要

PURPOSE: A system and a method for searching a document using a signature cache of a document are provided to recycle an initially search document search result using a signature cache, thereby shortening document processing time. CONSTITUTION: A data set generator(201) generates a signature data set using an ID data set extracted from a document set. An index data generator(202) generates index data about the ID data based on the ID data set. A document searcher(203) searches a document related to search target information.
