As the name implies, here you will find a list of seven search tools you may not know, but should. Even if you're a power user, this collection of tools and tips might surprise you. For example, Soovle puts a variety of search sites on a single page and as you type it show phrases each search site recommends. The new image search engine facesaerch (yes, "a" before "e") takes a Google image search, eliminates everything but faces, and gives the results a more modern interface.
Fasteagle rolls a search tool and a web directory into one interface, with a little touch of feed reader built in. The home page gives you quick access to search a dozen different sites, from Google and Delicious, to eBay and FriendFeed. There are many more. It's worth spending some time to check it out.
