The present invention is applicable to the technical field of data processing, and provides a big data stationery searching system, comprising a cloud database and a central control server. The cloud database comprises a data acquisition module, a data identification module, a data classification module, a data processing module, a data storage module, and a data sharing and publishing module. The central control server comprises a searching information input module, a data searching module, a data display module, and a data output module. Stationery data information acquired by the data acquisition module is identified by the data identification module; the identified stationery data information is classified and processed by the data classification module and the data processing module, and the classified stationery data information is stored in the data storage module; at the same time, the data sharing and publishing module publishes the stationery data information to the central control server; a user inputs searching information into the central monitoring server to find the desired stationery data information; the stationery data information is output by means of a mobile terminal. The present invention has wide coverage, high searching accuracy and speed, and requires less time.
