Knowledge@Wharton has brought an English-based network of knowledge communities to my attention, knuru, that offers a natural language search engine, mainly for business topics. The search returns two lists on tabbed pages: the first from the Knowledge@Wharton archives, the second from news sources. This is useful for those searches where Google’s lack of context awareness leads to a lot of unhelpful hits. Happy searching!

This one is great. I have tried it and there is very comprehensive news content as well as the Wharton stuff. Best part is that it takes your query and then pulls only the directly related content from the articles – so I don’t need to read whole documents. Highly recommend!
