Document retrieval method using an index file, document search server using the index file, and document retrieval program using an index file

摘要

PROBLEM TO BE SOLVED: To provide a method for enhancing the retrieval efficiency of a user by improving the precision of retrieval of a document file.;SOLUTION: A retrieval server 30 receives a retrieval key document file from a user terminal 20, and compares a retrieval object document index file pre-stored in association with a retrieval target document file collected/stored from an original document management server 10 with a retrieval key index file created based on the retrieval key document file. In this case, the server 30 counts not only matching of content data, but also the matching of combinations of attribute data and the content data, and the matching of the attribute data as evaluation points, and sorts the data including access key information to the retrieval target document file on the basis of the evaluation points and transmits it to the user terminal 20.;COPYRIGHT: (C)2007,JPO&INPIT
