3rd Posting: Search Engines


Mamma.com

'The Mother Of All Search Engines'

What is Mamma.com?
Mamma.com is a metasearch tool for finding web pages, news, pictures or mp3. It is a "smart" metasearch engine — every time you type in a query Mamma simultaneously searches a variety of engines, directories, and deep content sites, properly formats the words and syntax for each, compiles their results in a virtual database, eliminates duplicates, and displays them in a uniform manner according to relevance. It's like using multiple search engines, all at the same time.

Created in 1996 as a master's thesis, Mamma.com helped to introduce metasearch to the Internet as one of the first of its kind. Due to its quality results, and the benefits of metasearch, Mamma grew rapidly through word of mouth, and quickly became an established search engine on the Internet. Mamma.com's ability to gather the best search results available from top search sources and to provide useful tools to its users has resulted in its receiving multiple Honourable Mentions in the Best Metasearch category in the annual SearchEngineWatch Award.

What are the similarities between these search engine??

Well, as far as I concern, we use these search engine for one absolute reason which is to search for information. Mamma.com, Yahoo.com, Google and ericdigest provide convenient way for us to surf the online articles. The best part is, its just on one simple click. KLIK!!

How about the differences?

These search engines of course have differences somewhere. Like Mamma.com, when you search for a key word, 10 searching site work at the same time that provide you with information you want. Other than that, the sources and links are slightly different.
