Mamma.com is a metasearch engine that makes it easier and faster to find information by gathering the most relevant results from popular search engines, directories and deep content sites. You can search the Web, news, images, videos, yellow pages and white pages. Mamma displays results in a uniform manner according to its relevance for whatever your query can be. It's like using multiple search engines, all at the same time. It also provides a power search where you can choose the directories and index you want to search – such as Open Directory, Business.com, About.com, Ask.com, Gigablast, etc. – and set preferences like search speed, number of results-per-page, and length of descriptions, among others. You'll also find a great tool called mammas health that provides you with information concerning medications or other health-related topics, allowing you to get specific results about the health issues that matter to you, and a desktop search app that allows you to find files, emails, pictures, and music stored on your computer's hard drive in an instant.
