ABSTRACT:
An upper search on data to be searched is performed with a different condition from partial matching of a character string, and data items narrowed down thereby are counted. Then, it is determined whether the number of items obtained by counting is not more than the predetermined number of searchable items by partial matching Ls, and in relation to search results, a lower search is performed by partial matching of the character string.
