WIPO Patent Application WO/2022/270203

A1

Provided are a searching system, a searching method, and a searching program for searching for an item desired by a user. An assistance server (20) comprises a control unit (21) that is connected to a user terminal (10). The control unit (21) outputs, to the user terminal (10), a first item including a first component value in a plurality of principal components composing items, and a plurality of item candidates including component values that are different from the first component value. The control unit (21) specifies a second item selected in the user terminal (10) from among the plurality of item candidates. The control unit (21) calculates, for each of principal component values, the positional relationship between the first component value and a second component value of the second item. The control unit (21) calculates, for each of the principal component values, a distribution of the component values according to the positional relationship. The control unit (21) newly generates, for the second item, a plurality of item candidates on the basis of the distribution of the component values. The new item candidates are output to the user terminal (10).
