The application discloses a business object search system, method and device, as well as related methods, devices, systems and equipment. Wherein, the business object search method includes: receiving a similar business object search request for the target business object; obtaining the first attribute decoupling representation vector of the target business object and the candidate business object; decoupling the representation vector and attribute value difference information according to the first attribute , determine from the candidate business objects the business objects that have attribute value difference information on the target attribute and are the same or similar to the target attribute on the non-target attribute; and return the similar business object to the requester. Using this processing method, on the one hand, can effectively increase the search dimension of single-factor control search, achieve the search effect based on the user's mind, thereby improving user experience; on the other hand, it can effectively improve the recall and accuracy of search results.
