A Search Engine is a software system that is designed to carry out web searches. It allows the users to look up information on the World Wide Web ( WWW), known as the Internet. The search engine achieves this by looking at many web pages to find matches to the user’s search inputs. It returns results, which are ranked by relevancy and popularity by the search engine. Some very popular search engines are Google Search, Yahoo! Search, Ask.com, etc. Web search engines have changed our world. The search results are generally presented in a line of results and they are often referred to as Search Engine Result Pages ( SERPS). The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files.
BIRTH OF SEARCH ENGINES :
Modern search engines are pretty incredible – complex algorithms enable search engines to take the search query and return results that are usually quite accurate. Search engines have come a long way since their early prototypes. Search engine history all started in 1990 with Archie ( an FTP site) hosting an index of downloadable directory listings. The first search engine was developed by Alan Emtage, a student at Mc Gill University in Montreal. One of the most well-known directories was DMOZ, created in 1988 by two engines at Sun Microsystems. The directory became the default way of finding information on the web for many, with a search function for faster directory navigation. Web Crawler, launched in 1994, was the first search engine to be widely used, as well as the first to fully index the content on web pages. The first popular search engine on the web was Yahoo! Search. It became one of the most popular ways for people to find web pages of interest. Soon after, a number of search engines appeared and vied for popularity. These included Magellan, Infoseek, Alta Vista, etc. Google adopted the idea of selling search terms in 1998, from a small search engine company named Goto.com. Around 2000, Google’s search engine rose to prominence and the rest is history. By the turn of the century, the web had entered most aspects of our lives from communication to e-government, e-commerce, and e-learning, making it much more than just an informational repository.
