Abstract: An information processing method and apparatus, where the method includes: obtaining a user information table; creating, based on the user information table, a bitmap index including a plurality of bitmap vectors; creating a user identifier array based on the user information table; receiving a query request sent by a client; querying the user information table based on the bitmap index, the user identifier array, and at least one attribute value, to obtain a query result; and sending the query result to the client. In the foregoing manner, second-level indexing for an ad hoc query can be implemented.
