Abstract: A method for displaying a set of results in a client system comprises first sending an information request having at least a word string to a server system. The server system then selects an application service, which provides a set of results. The server system then transmits an information package corresponding to the application service. Finally, the client system displays a set of results corresponding to the application service in a display area in the client system based on the information package, and also sends a user package having the set of results back to the server system. This user package is processed by at least identifying zero or more application services attributable to the word string based on the set of results.
