Search Engines

A search engines is a program that search's web pages for specified keywords and returns a list of the pages where those keywords were found. Google, Bing and Yahoo! are examples of search engines that enable users to search for documents, images, pages and programes on the World Wide Web.

A search engine uses software robots, called spiders to build a database of the words found on Web sites, a process known as crawling. The spider will crawl a site, indexing the words on its pages and following links found within the site.

These indexed words and links are stored in huge database servers, then when a user enters a search query the search engine looks through its indexed library and returns the results. There could be millions of results based on the keyword(s) used, so it uses an algorithm to rank the page which determines which order to display the results.

The algorithm could look at how many times a keyword is placed on a page, the relavancy of the page or page title.

The different search engine providers use variations to their algorithm's to decide on where a web page is ranked. For example stop words ("in", "and", "the" etc) are filtered out by some search engines while others will index these words.

As trends change, the algorithm's are updated to return better results for the user. Bing recently started including related information from social networks such as Facebook, Twitter and Google+.
