The search for the best search engine
Google - Link
Its success was based in part on the concept of PageRank based on popularity , under the premise that the most desirable pages were linked by other pages more than the rest. This idea allowed Google to have the pages of a specific search based on their importance , based on this algorithm , ie, the more pages linked by other pages are displayed first. The minimalist interface Google became very popular among users and since then has had many imitators
Google and many other search engines not only used PageRank , but over 150 criteria to determine the relevance of a page . The key features of this search engine will be presented in the following form .
yahoo - Link
In 2004 , Yahoo launched its own search engine based on a combination of technologies from its acquisitions and providing a service which already prevailed search sites on the directory .Its best feature is probably the integrated homepage. It not only counts with other services such as those in google, including e-mail, but also incorporates others such as yahoo questions, where other users can answer. Also, instead of using a minimalistic interface such as google does it has decided to use a sort of homepage where you can access to news, email and others. This in my opinion is an advantage against google.
live - Link
The most recent of the major search engines is Live (formerly MSN Search) , from Microsoft , which previously relied on others to post their searches. In 2004 he debuted a beta version with their own results , driven by its own robot (called msnbot ) . Early in 2005 he began the final version.
The market is now dominated by Google , Yahoo and Microsoft . The other big search engines tend to be sites that show the results of other search engines and also offer other types of content that are more or less importance on the page itself as does Yahoo!
ask - Link
Ask is a search engine where you can ( as the name says in English "ask" is asking) ask for what you're looking for , whether you are looking for the answer to a question or just want to find a particular file .
Search with a nice graphical interface, provides services in Web search , image search , video, and Directions Maps , News, and a session of searches for online purchases .
The truth is it is a quite limited user services finder .
thumbshots - link
Thumbshots is a search engine that is based on results from other search engines ( metasearch but is not ) , because in the case of querying only be carried out on two types of search engines.
Thumbshot has a very special feature because it makes comparisons between two search engines, evaluates what their pages in common, assesses how many web pages retrieved each of the engines and compares them to the user is to an idea that search engine is better with respect to the subject you are considering in the search.
