Google has unveiled Caffeine, a "next-generation architecture" for its Web search platform.
The new search engine is said to be faster, more accurate, and more comprehensive than the current Google search setup.
Google is one of the Internet's most dominant search engines. It accounted for about three-quarters of all U.S.based searches in June, according to Web metrics company Hitwise.
Google has set up a Web developer preview of Caffeine that you can test at http://www2.sandbox.google.com/.
That site only works on a regular Web browser as of now; you can't test it via your mobile phone just yet.
