description Embodiments of the invention provide a data retrieval method and apparatus. The data retrieval method is applied to the data retrieval apparatus. The method comprises: constructing two same index libraries corresponding to basic data as a retrieval object; when auxiliary data as a retrieval object is obtained, determining a to-be-reconstructed first index library from at least one index library not subjected to data retrieval currently; and according to a retrieval object corresponding to the first index library currently and the auxiliary data obtained currently, reconstructing the first index library. The method further comprises: when a data retrieval request is obtained, determining a to-be-utilized second index library from at least one index library not subjected to reconstruction operation currently; and based on the second index library and a corresponding retrieval object, determining a retrieval result corresponding to the data retrieval request. Through the scheme, the influence on a response to th
