The invention aims at providing a method and equipment for performing cache management on retrieval data. The method comprises the following steps of: retrieving the cache management equipment to obtain the retrieval attribute of a query sequence; detecting whether the retrieval data corresponding to the query sequence and stored in a first cache space meet the first trigger condition of migration according to the retrieval attribute; and if the first trigger condition is met, migrating the data to a second cache space from the first cache space. Compared with the prior art, in the method provided by the invention, dynamic migration for the retrieval data is realized by detecting the trigger condition of the migration for the retrieval data, so that the characteristics of the different cache spaces are adequately utilized, thus increasing the accuracy of performing data retrieval in the cache spaces, ensuring the execution efficiency of the data retrieval, and effectively decreasing the use cost of the cache spaces.
