Abstract
Methods and apparatuses for updating and searching a graphic code are disclosed. The apparatus receives a graphic query request carrying a graphic code to be searched. If no product information corresponding to the graphic code is found in the graphic code database, the apparatus searches for a recommended keyword corresponding to the graphic code; if a recommended keyword is found, the apparatus returns the recommended keyword, and if not found, returns a search box. The apparatus then receives a search request carrying a search keyword, and, if the search keyword is determined to be inconsistent with the recommended keyword corresponding to the graphic code, makes the search keyword a new recommended keyword of the graphic code, and adds the new recommended keyword to the graphic code database.
