This is quite different from others. This will only show you some alternatives of your keyword. Let me explain by an example. Lets consider, I want to buy a mobile phone. But I know only one brand NOKIA. Searching for NOKIA will show some other alternatives like iphone, samsung, motorola, sony ericsson, blackberry, siemens.

Here I set the search varieties to “Recipe” and searched for “rice”. It gave all the recipes with rice.

Oh my God……… This is really a very exciting search engines which will give data about a person. Just type his/her name or email or user name or phone, it will give you details about that person. Honestly saying, I had never seen such type of websites before. It gives the details like: user name, profile photos, the places where I have signed up, Picassa photos etc. Among all of the above search engines I like this the most.
loved the design of justhearit.com
whereisdoc.com is also useful…nice collection
