Search device, search system, search method, and computer readable medium

A search system comprising:

• a management device 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;
• and
• a search device that transmits a search condition to the management device,
• the search device including
• processing circuitry to:
• perform grouping on a plurality of search-target numerical values to be searched for, each of said search-target numerical values being 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;
• generate, 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 generate the search condition by integrating the search condition element of each numerical value group;
• and
• transmit the generated search condition to the management device.

A search method by a computer that transmits a search condition to a management device 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, the search method comprising:

• performing grouping on a plurality of search-target numerical values to be searched for, each of said search-target numerical values being 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;
• generating, 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 generating the search condition by integrating the search condition element of each numerical value group;
• and
• transmitting the generated search condition to the management device.

A non-transitory computer readable medium storing a search program for a computer that transmits a search condition to a management device 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, the search program causing the computer to execute:

• a grouping process to perform grouping on a plurality of search-target numerical values to be searched for, each of said search-target numerical values being 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 process to generate, 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 generate the search condition by integrating the search condition element of each numerical value group;
• and
• a transmission process to transmit the search condition generated by the search condition generation process to the management device.
