<P>PROBLEM TO BE SOLVED: To provide an information search system which realizes online updating of search indices without the need to prepare two systems of physical storage for storing copies of indices, namely one for searching and the other for updating. <P>SOLUTION: By means of a snapshot function provided by an OS, duplicates of original indices are created. A search engine is attached to those duplicates and utilized while an index update process is applied to the original index data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
