Patent ID: 11106740

Abstract:
A search device (300) transmits a search condition to a management device (400) that manages a numerical value which is a number sequence of one or more digits, based on a digit-by-digit correspondence between a number of each digit of the numerical value and a digit representation which is a symbol representing a digit. A grouping unit performs grouping on a plurality of search-target numerical values to be searched for, each of which is a number sequence of one or more digits, on a basis of commonality of the number of digits and commonality of a number sequence from a most significant digit, so as to generate one or more numerical value groups. A search condition generation unit generates, for each numerical value group, a search condition element by establishing a correspondence between a number of each digit of a sequence common range, which is a range of a number sequence common to search-target numerical values included in each numerical value group, and the digit representation of each digit of the sequence common range, and generates the search condition by integrating the search condition element of each numerical value group. A transmission unit (305) transmits the search condition generated by the search condition generation unit to the management device (400).
