Search Engine and its Basics
Web Search Engine or Simply Search Engine are designed to search the information in the world wide web. In the modern world more than half the population in the world use Internet daily to find information and things online. Internet is actually a collection of FTP (File Transfer Protocol) sites that users could access to download or upload files.
As like the web directories which is maintained by the manually by the human,, search engines also maintain real time information by running an algorithm web crawler. There are certain agents which saves the web page in a related database and these agents are called as crawlers, spiders or robots. The work of these agents is to crawl the web page store the information of the webpage in database by means of indexing. So when the user types something in the search, it results in showing the relevant result which is fetched form the website database.
The first real search engine, in the form that we know search engines today, didn’t come into being until 1993. It was developed by Matthew Gray, and it was called Wandex. Wandex was the first program to both index and search the index of pages on the Web. This technology was the first program to crawl the Web, and later became the basis for all search crawlers. And from there, search engines took on a life of their own. From 1993 to 1998, the major search engines that you’re probably familiar with today were created:
Excite - 1993
Yahoo! - 1994
Web Crawler - 1994
Lycos - 1994
