The fact is that there are a lot of search engines that work like Google. To get Google off its throne, but so far, no search engine is powerful enough to replace Google.

What is a search engine – a brief history?

Purpose of invention Web search engines are to search for information on the World Wide Web. The user of this search enters the keyword to get the desired information, and this provides maximum search results related to it. These search results are also called SERPS or Search Engine Results Pages. Results include web pages, images, information, and a variety of files. 

The web directory is created by human editors but works from a combination of search engine algorithms or algorithms and human input.

Archie became the first tool.

There was a list of web servers in the web’s early development stages, and Tim Berners-Lee edited this list. Web servers are hardware or software that transmits content that falls on the Internet to the user.

Tim Berners is a British computer scientist. He invented the World Wide Web.

Its host server was CERN. Then as the new webserver went online, the list server designed by the team could not carry the load of this server. Shortly afterward, the National Center for Supercomputing Applications’ website displayed the servers with the caption, “What’s New!” Then came Archie. It was the first search engine available on the Internet. It was created in 1990 by Barbados-based scientist Alan Emtage and his colleagues. Archie was displaying all public files on the Internet to the user, But Archie couldn’t make any indexes. That was his weak point.

What is the first search engine?

The first search engine came in 1993.

Archie was followed in 1991 by a protocol called Gopher. It had two search programs called Veronica and Jughead. This program displayed the data available on the Internet in a molded manner, which was its feature. However, these programs did not last long. Despite such development, in 1993, there was no search engine available. At the time, the work was being carried out by a human-edited web directory. On September 2, 1993, the world’s first primary web search was launched. It was called the W3 Catalog. It was produced by Oscar Nierstraz of the University of Geneva. Then in 1993, two new search engines were launched, Aliveb and Jumpstation.

The challenge of full-text search

Many scientists throughout the world were working on the development of search engines. Although, search engines created in 1993 could not search the full text. Full-text search meant a search in which the search engine would search for the user’s word in each file and give matching results. In 1994 came a browser called Web Crawler. It was the first full-text browser in the world. It also became popular among ordinary people. 

All engines manufactured since then have been developed based on the same engine standards. The most popular Google search is available in 124 languages ​​worldwide.

Web Indexing

This is the second stage of the search. It lists the entire information collected by the crawler. The entire information obtained at this stage is collected in the database. This database depends on the page’s structure and the order of the other pages associated with a page. This is called web indexing.


The third stage of the search engine is called searching. It works as a search software. When a user enters a keyword or word to search for information, the software displays search-related content through a pre-created database or by looking at an index.
