Hi, chk out this link http://beta.previewseek.com/ Superb Search Engine!Perhaps going forward we will be using this more than Google ?? Also preview seek is more intelligent than google! You type 'Mercury' in google and it will also show you results of Planet mercury even if you are looking for info on the element called Mercury. Where as in PreviewSeek first you get different categories of mercury (Planet, Element and what not!) and from there you can proceed only into that category. Even a search for DSC 80, a sony digi cam gave astonishing result sets with also categories on left side to preview its reviews or to buy it. Good luck PreviewSeek, check it out at beta.previewseek.com . Note that it is still in beta! No source, just got a mail.
