摘要

PROBLEM TO BE SOLVED: To provide a set attribute retrieval system efficiently executing a retrieval processing.;SOLUTION: When, for example, a filter condition, or a logic product between a condition related to a set attribute and a condition related to a general attribute and not a set attribute is inputted, a filter retrieval execution means 121, at first, allowing an attribute search means 122 to retrieve an entry satisfying the condition related to the general attribute from an entry/attribute storage means 131, reading a management entry satisfying the condition related to the set attribute, erasing an entry satisfying the condition not within an effect range of the read management entry and satisfying the condition of the general attribute, and delivering the result to a result output means 104. This method can eliminate candidates compared with a case where the management entry satisfying the condition related to the set attribute is read out first and whether or not it is within the effect range of the management entry is searched with the whole entry set as the candidates, so as to efficiently execute the retrieval processing.;COPYRIGHT: (C)2004,JPO
