Almost anything you type to search, Google will find it for you. It is the world's leading search engine, and is constantly improving. Other services from Google include maps, translations, finances, etc. It's the only search engine I use and recommend.
Two things need improvement: (1) the search engine caters too much to paid advertisers (2) customer support and bug reporting is ineffective. Some of their truly fantastic services (such as Reader) are awkardnessful enough to learn that regular people can't see their value.
