The invention provides an object combination recall method and device, electronic equipment and a storage medium. The method comprises the steps of receiving a user search request sent by a target user through a target terminal; determining a target user feature vector corresponding to the target user identifier; determining an object combination feature vector corresponding to each to-be-recommended object combination based on the target user feature vector and the object feature vector of each to-be-recommended object in each to-be-recommended object combination; and calculating the similarity between the target user feature vector and each object combination feature vector, and recalling the to-be-recommended object combination corresponding to the object combination feature vector of which the similarity is greater than a preset similarity. Visibly, the user feature vector can represent a plurality of interest points of the user, and the object feature vector has a cross-site generalization capability and
