PROBLEM TO BE SOLVED: To accurately perform a similarity search using a feature quantity vector. ! SOLUTION: In a search device 100 of the present embodiment, a reverse stereoscopic projection unit 104 reversely, stereoscopically projects a feature quantity vector to a hypersphere divided into a plurality of hyperplanes, a bit string generation unit 105 specifies a bit string on the basis of the projection result, and at this time, an arrangement unit 106 sets an initial position of each hyperplane. For example, the arrangement unit 106 sets the initial position of each hyperplane so that the intersection point of each hyperplane is included in the hypersphere S. !
