Search Multiple Search Engines At Once
Perform one search across muliple search engines simultaneously.
Search engines: Google, Yahoo, Bing, Ask, AllTheWeb, AOL, Lycos, DogPile, AltaVista, Clusty.
Individual capabilities of search engines are preserved [Web, Images, Videos etc]
I don't think that you can beat Google in most circumstances/search situations [non specialist (non scientific etc)] But another option can sometimes be helpful.
