Another group of Internet search services are called metasearch engines.
Yippy is an example of a metasearch engine.
These services each have their own focus or specialized use. Some run your search terms through several search engines at once while others are best for locating particular sources such as videos or blogs.
One of the advantages of Yippy is that it clusters your search results into subcategories, or "clouds," that can help you navigate your results more easily. Give it a try!
Be sure to learn about each metasearch engine's focus and features to select the one that best matches what you are looking for.
