<p>The present invention desires to provide a method and apparatus for assisting query, a method and device for querying, and a naming query system. Specifically, the method of assisting query may, for example, comprise: acquiring a record that includes a unique identification and at least one piece of dimension information associated with the unique identification, wherein each piece of dimension information includes a sequence of attributes, each attribute being ordered in the sequence in accordance with a hierarchically progressive relation; calculating a hash value for an attribute pair comprising attributes of every two neighboring levels; and storing, in association with the hash value, the unique identification in at least one storage device. The method of querying comprises: receiving a query; calculating one or more hash values; in response to the one or more hash values matching stored have values in at least one storage device, deriving an intersection of unique identifications that are stored in association with the matched stored hash values; and returning at least one unique identification included in the intersection as a query result.</p> |
