The article Aarontay pointed to seems to suggest that Kosmix searches deep web content. But when I tried the suggested search for ravioli the top hit in the results is from wikipedia (although fatsecret content, as discussed in the article, does appear lower down - assuming this is "deep web" content). It does sound very much like Kosmix is still in development - so perhaps wikipedia will fall down the list later on?
What I liked about Kosmix is that is shows up Facebook and Twitter content on the right hand side and my search for library showed up tweets posted less than a minute ago. I liked that very much.
Anyone using Kosmix?
Anyone using any other search engines that might not be well known?
Getting any interesting results?
