Retrieval method and storage device

The invention relates to the technical field of data retrieval, in particular to a retrieval method and storage equipment. The retrieval method comprises the following steps: responding to a retrieval instruction, obtaining a retrieval keyword, and generating an identification string according to the keyword; performing data calling in a cache server according to the identification string, if the data is obtained, returning the data, and if the data is not obtained, inputting the retrieval keyword to a pre-trained knowledge map to obtain a preset number of target keywords; a retrieval request is initiated to a database according to the target keyword, and a retrieval result is returned; and storing the identification string and the retrieval result to the cache server. According to the method, the access to the database is avoided, the response speed is improved, the access to the server where the database is located is reduced, and the burden is relieved. 本申请涉及数据检索技术领域，特别涉及一种检索方法和存储设备。所述一种检索方法，包括：响应检索指令，获取检索
