Abstract

A search device includes a memory, and a processor coupled to the memory and the processor configured to calculate a plurality of evaluation values relating to a plurality of items respectively, in accordance with differences between a plurality of search conditions including the plurality of items, in response to receiving a new search condition, perform a search process based on both the new search condition and the calculated plurality of evaluation values, and output a result of the search process.

Claims

1. A search device comprising:

a memory; and

a processor coupled to the memory and the processor configured to

calculate a plurality of evaluation values relating to a plurality of items respectively, in accordance with differences between a plurality of search conditions including the plurality of items,

in response to receiving a new search condition, perform a search process based on both the new search condition and the calculated plurality of evaluation values, and

output a result of the search process.

2. The search device according to claim 1, wherein

the plurality of evaluation values are calculated in accordance with input order of the plurality of search conditions.

3. The search device according to claim 1, wherein

the search process includes changing the new search condition into a specific search condition based on the plurality of evaluation values, and performing a search by using the specific search condition.

4. The search device according to claim 1, wherein

the plurality of search conditions is input by a first user.

5. The search device according to claim 1, wherein

the differences include a difference between a first search condition input first among the plurality of search conditions and a second search condition input next.

6. The search device according to claim 1, wherein

the processor is configured to update the plurality of evaluation values in accordance with other differences between other plurality of search conditions.

7. The search device according to claim 1, wherein

the plurality of items includes a price item, and

the plurality of evaluation values are calculated in accordance with a difference expressed by a direction of change in a second value of the price item included in a second search condition input after a first search condition among the plurality of search conditions as compared with a first value of the price item included in the first search condition.

8. The search device according to claim 1, wherein

the plurality of items includes a region item, and

the differences include a difference expressed by at least one of larger, smaller, and different determined by a second value of the region item included in a second search condition input after a first search condition among the plurality of search conditions as compared with a first value of the region item included in the first search condition.

9. A computer-implemented search method comprising:

calculating a plurality of evaluation values relating to a plurality of items respectively, in accordance with differences between a plurality of search conditions including the plurality of items;

in response to receiving a new search condition, performing a search process based on both the new search condition and the calculated plurality of evaluation values; and

outputting a result of the search process.

10. The search method according to claim 9, wherein

the plurality of evaluation values are calculated in accordance with input order of the plurality of search conditions.

11. The search method according to claim 9, wherein

the search process includes changing the new search condition into a specific search condition based on the plurality of evaluation values, and performing a search by using the specific search condition.

12. The search method according to claim 9, wherein

the plurality of search conditions is input by a first user.

13. The search method according to claim 9, wherein

the differences include a difference between a first search condition input first among the plurality of search conditions and a second search condition input next.

14. The search method according to claim 9, further comprising:

updating the plurality of evaluation values in accordance with other differences between other plurality of search conditions.

15. The search method according to claim 9, wherein

the plurality of items includes a price item, and

the plurality of evaluation values are calculated in accordance with a difference expressed by a direction of change in a second value of the price item included in a second search condition input after a first search condition among the plurality of search conditions as compared with a first value of the price item included in the first search condition.

16. The search method according to claim 9, wherein

the plurality of items includes a region item, and

the differences include a difference expressed by at least one of larger, smaller, and different determined by a second value of the region item included in a second search condition input after a first search condition among the plurality of search conditions as compared with a first value of the region item included in the first search condition.

17. A non-transitory computer-readable medium storing instructions executable by one or more computers, the instructions comprising:

one or more instructions for calculating a plurality of evaluation values relating to a plurality of items respectively, in accordance with differences between a plurality of search conditions including the plurality of items;

one or more instructions for, in response to receiving a new search condition, performing a search process based on both the new search condition and the calculated plurality of evaluation values; and

one or more instructions for outputting a result of the search process.
