Clusty

Recently tried clusty, a clustering search engine.
I usually use google, but when I didn't find what I was searching for I tried clusty, and found.
Don't know if this clustering thing is of any use, it enables to categorize your search in a different way... Sort of post-processing.
Just like google, clusty has web, news, images, shopping searches, also has wikipedia, blogs and jobs searches.
Note: Google's blog search is currently beta.

BTW, when looking for alternatives to google, I had a look to mozdex. This is an open source search engine, currently beta. With not much activity during last year. It seems a lot of buzz followed it's opening (in 2004), but nothing followed. I guess it's dead.
