An information processing apparatus receives a query specifying a value range; generates keys indicating values in the query; generates a key range (KR) group containing at least one KR which is a set of prescribed keys; stores a key indicating bounds of keys managed by each apparatus; receives the KR group; specifies, with respect to each KR in the received KR group, one key as an address key based on the relation between the value indicated by a prescribed key contained in the KR and the values indicated by each stored key respectively; appends the keys contained in the KR to a group of KR which is a set of keys associated with a node identifier of an apparatus identified based on the value of the specified address key; and forwards each group of KR to the apparatus identified by the node identifier associated with each group of KR respectively. |
