From Seo Wiki - Search Engine Optimization and Programming Languages
Zuula is a metasearch engine that provides search results from a number of different search engines. Zuula can be used to carry out standard web searches, image searches, video searches, news searches, blog searches, and job searches. Results are available from major search engines, such as Google, Yahoo, and Bing, and smaller engines, such as Gigablast and Mojeek. Zuula is a trademark of Zuula LLC.
Unlike many metasearch sites, Zuula does not combine the results from its source search engines. Instead, Zuula uses tabs to organize the results from source engines. When a user carries out a search, the first results that are displayed are those from the search engine assigned to the first tab. The user can then click on other tabs to see the results from other source engines. (Users can change the order of the tabs for each search type by simply moving them into the desired order.)
