CrossEngine

CrossEngine is a search tool similar to Trovando. You type in your search terms just once and then click on each search engine in turn to run the search. The search tools are grouped under tabs by type, for example standard, video, images, news, blogs. Two groupings that CrossEngine has but Trovando does not are Formats, which enables you to search for file types such as PowerPoint or Excel, and Social covering services such as Delicious, Furl and Squidoo. Audio search is included under Formats, which I find a bit odd. It makes more sense to me for that to have its own tab or be included with video as it is in Trovando. Overall, a neat tool if you want to quickly run your search in several different tools one by one.
