Google will be holding a press conference today to unveil new search features including the Search as you type results. However, you do not have to wait till Google unveils it to the public to start using it.
Google’s Instant Search results page is already up and you can use it to see how the new interface works by heading to this URL. Using the search box provided, you can type in your search query and the results will update as you type.
I tried it out for several queries and not only is it super-fast, it also is very useful when you might not be sure what exact search keywords you should use. This is fantastic, go give it a try here.
