Vector index recall method and device, electronic equipment and storage medium

The invention discloses a vector index recall method and device, electronic equipment and a storage medium. The method comprises the following steps: when a request network packet sent by an upstreamservice application party is received, carrying out data analysis on the request network packet to obtain a corresponding vector expression; determining a scene demand parameter of an upstream serviceapplication party, and determining a corresponding target configuration parameter from a pre-established first configuration file according to the scene demand parameter; Selecting a corresponding index retrieval algorithm and an index library according to the target configuration parameters; Matching the vector expressions with vector indexes in a corresponding index library by adopting a corresponding index retrieval algorithm, and recall the matched vector indexes. According to the method, the vector index recall can be realized, and meanwhile, the accuracy, the efficiency and the cost canbe considered. 本发明公开了一种向量索
