Patent number: 9529919Abstract: A system and method for providing a suggested store at or through which to purchase a product or service. When a user enters a query for a product or service into a user interface, the system may use the query as a search argument to search files to find one or more pictures illustrating information about a product or service represented by the query. The picture could illustrate where the queried product or service may be purchased. Auto-complete processes may also be used to process the query as it is being entered, to generate an auto-suggestion key word based on fewer than all the letters of the query, to use as a search argument for the search. Both the query and the auto-suggestion key word may be used as search arguments to find the relevant picture in a variety of search logic sequences to provide the picture to the user.Type: GrantFiled: July 23, 2014Date of Patent: December 27, 2016Assignee: PAYPAL, INC.Inventors: Xiaodi Zhang, Jun Hang
