Claim:
1. An information retrieval system comprising: a mobile communication terminal that independently performs a retrieval service provided by a server that is placed outside a vehicle; and a vehicle device that is equipped to the vehicle and operates in cooperation with the mobile communication terminal to perform the retrieval service via the mobile communication terminal, wherein the vehicle device includes: a vehicle-side display portion that displays information related to the retrieval service; a vehicle-side manipulation portion that has a first vehicle-side input section and a second vehicle-side input section, wherein the first vehicle-side input section enables an input of an intended keyword to be searched by multiple times of user manipulation, the second vehicle-side input section is preliminarily assigned with a frequently used keyword and enables an input of the frequently used keyword directly by single time of user manipulation, and the frequently used keyword is a keyword that is frequently used by a user in the vehicle; and a vehicle-side control portion that executes a retrieval process based on a vehicle-side keyword that corresponds to one of the intended keyword inputted via the vehicle-side manipulation portion or the frequently used keyword inputted via the vehicle-side manipulation portion, wherein the vehicle-side control portion transmits the vehicle-side keyword to the mobile communication terminal during the retrieval process, controls the mobile communication terminal to retrieve information related to the vehicle-side keyword by performing the retrieval service, acquires a retrieval result from the server via the mobile communication terminal, and controls the vehicle-side display portion to display the retrieval result as the information related to the retrieval service, and wherein the mobile communication terminal includes: a terminal-side display portion that displays information related to the retrieval service; a terminal-side manipulation portion that has a first terminal-side input section and a second terminal-side input section, wherein the first terminal-side input section enables an input of the intended keyword to be searched by multiple times of user manipulation, the second terminal-side input section enables an input of a predetermined keyword by at least two times of user manipulation; and a terminal-side control portion that transmits, to the server, a terminal-side keyword corresponding to one of the intended keyword inputted via the terminal-side manipulation portion or the predetermined keyword inputted via the terminal-side manipulation portion, acquires a retrieval result transmitted from the server, and controls the terminal-side display portion to display the retrieval result as the information related to the retrieval service; wherein, when a case in which the vehicle device performs the retrieval service by executing the retrieval process based on the vehicle-side keyword inputted to the second vehicle-side input section is compared with a case in which the mobile communication terminal independently performs the retrieval service based on the terminal-side keyword inputted to the terminal-side manipulation portion, a quantity of the user manipulation performed on the second vehicle-side input section of the vehicle device is less than a quantity of the user manipulation performed on the terminal-side manipulation portion of the mobile communication terminal.
