Yahoo Inc is rolling out a service that lets users in the United States tap the Internet media giant's Web search using text messaging, matching a service now offered by rival Google Inc.
Yahoo also said that it was expanding its Yahoo Search on Mobile, which was previously available only on advanced phones such as the Treo. Now, the service yields a full Web search on virtually any phone with a color screen.
The latest mobile search move by Yahoo comes as Web search firms are looking to boost business by providing services to users while they're on the go and away from their personal computers.
Both the SMS Web search and the Yahoo Search on Mobile services use shortcuts that take less time for users to input their queries.
A user would send a text message to shortcode 92466, which spells Yahoo on a telephone keypad, with the text "pizza 94104" to retrieve a list of pizza restaurants near that Zip code.
