What Search Engines Miss

This U C Berkeley Website offers information about differences between the three main search engines: Google, Yahoo and Ask.com. But these major search engines generally function in the same way.

There are specialized and unique search engines, for example, RollYo and Mammathat eliminate duplication and make searching easier.  Dogpile adds another layer of efficiency as it brings all the search engines together on one convenient page.

Now there is what is called the Deepnet or the Invisible Web which needs attention when we talk about search engines. Search engines are only able to see certain documents on the Internet.  U C Berkeley and Wikipedia both have articles on the hidden web although a lot of the documents that used to be hidden are becoming more and more visible.

As I was saying, there is so much that other search engines are unable to see or crawl. A new search engine, Cuil pronouced to rhyme with cool, has come up claiming to can “search 121,617,892,992 web pages” a lot more websites than Google, the current top search engine. Check out this Cuil search engine.
