 How the search engine work

​

Search engines send out “web crawlers” or “spiders” (automated computer programs that browse the internet in a methodical and automated manner) to create a copy of all the web pages they have been to so the search engine can then index the pages to create web site listings that facilitate faster searches.  A user types a query into the search engine and the search engine then sorts through millions of pages in its database to find a match to that specific query.  The search engine then produces the results to your query in a ranked order according to relevancy.

Example of search engine :

​

www.google.com

 

www.yahoo.com

​

www.bing.com
