Provided is a means for displaying the results of search, which are provided by one of two different search systems, using the other search system, and enabling continuous searching. One search system includes a search takeover data production command that is used to output search takeover data which represents a list of identifiers of articles on the results of search. Another search system includes a search takeover data reading command that is used to read search takeover data. A document identifier correspondence table is used to associate the identifiers, which are specified in the search takeover data, with identifiers understandable by the latter search system. When a user clicks a search system transfer instruction button included in an interface included in one search system, the search takeover data producing command is executed to produce search takeover data, and the search takeover data is passed to an interface included in another search system. The latter search system regards the list of identifiers of articles, which has been passed according to the search takeover data reading command, as the results of search, and thus operates continuously.
