The World Wide Web evolves from Search to MultiSearch.

Search engines were designed to help people find information in the World Wide Web more easily. They are information retrieval systems that minimize the amount of time and information users have to deal with when they carry out a search. Google, MSN (known now as Live Search), Yahoo!Search, Ask.com and WiseNut are some of the most popular ones. These search engines use automatic tools as spiders or robots to index web pages of registered sites.

Search engines have evolved to multisearch a multi tasking search engine that enables users to gather information from one or more search engines at the same time. This type of system combines traditional search engines and metasearch engines characteristics with the additional advantage of being able to recover previous search results classified by users. Search engines have evolved to multisearch to take advantage of both automatic tools and combine them with result classifications made by humans.

There are several advantages for users who turn to multisearch: improve search accuracy, reduce searching time, increase results relevance and simplify information management. Some of the multisearch websites operating at the moment include: iTools, Dogpile, Wookah and Ixquick. Although these multisearch engines base themselves in the same idea, they operate differently:

1.iTools shows you a list of search engines you can choose from to carry out a search.

2.Dogpile shows you a list of results of four search engines, Google, Yahoo! Search, Live Search and Ask.com

3.Wookah shows you the best sites for your search at the same time, on one screen and under different tabs.

4.Ixquick very similar to the first two, it shows you a list of results in different search engines.

Multisearch engines can be classified into two: list search engines very similar to the traditional search engines and simultaneous search engines allowing the user to obtain and display several websites on one screen. Although users generally prefer simultaneous search engines because they are visually more appealing and generally provide a wider range of functions they can be slower than list search engines.
