Google bolsters mobile search

update Google introduced on Tuesday two new search options for mobile phones.

One feature lets people with browser-enabled cell phones use Google Local--a Web directory of local businesses and sights--by typing in a name and ZIP code. Using the second feature, people can text message Google SMS (Short Message Service) with the short code "46645" to receive driving directions to most locations. The services build on Google's existing mobile search efforts, which were launched in 2001. The Mountain View, Calif.-based company lets people search its Web and images index from mobile devices. It introduced SMS search late last year.
