What is the most fast search engine?

AlltheWeb is famed for giving Google a run for its money. It often overtook Google in terms of the number of pages indexed, only to be outdone by the latter in a matter of a few days. Alltheweb is also famous for its simple page layout. One of the somewhat unique things about AlltheWeb is that it will give results including different pages of the same site. AlltheWeb is still able to compete with Google; for example, it allows for searching of only audio files, which is something Google and most other search engines are not able to do.
