What is the History of the Search Engine

The World Wide Web is an important asset for the modern man in his avid search for more and more information. But any Internet surfer knows that this asset has no use without its navigation tools. The search engine is used now commonly by any surfer, but its history goes a long way back.
What is a search engine?
A search engine is a tool or a program that enables users to search and retrieve specific documents on the Internet using specified keywords. The search engine has few components, such as: spider software, search engine software, rules for ranking and a database.
How did it all start?
You may be surprised, but the Internet has its beginnings in the late 6o’s. It was during the cold war, when the Americans were searching for a way to avoid loosing their line communications, that they started developing the Arpanet – the ancestor of the today’s Internet. In the 80’s, after seeing the benefits of this kind of network, many universities started creating one of their own. Along the years, many other important institutions started connecting to the net using the TCP/IP. Thus, the Internet was born. As the net expanded and was used more and more, the need for a search engine was felt. The first search engine, named “Archie”, was the idea of Alan Emtage. This was happening in 1990 when the World Wide Web didn’t exist yet. “Archie” used the File Transfer Protocol server to share files over the network. If a person wanted to share files over the Internet he had to install the FTP server. Whoever wanted to access these files would just have to connect to this server’s IP address by using a FTP client and obtain the requested files. “Archie” searched the Internet for FTP sites and indexed the found files. It made it possible for users to find files matching their search requests. This is how the birth of the first search engine took place.
In 1991, Mark McCahill from the University of Minnesota created another search engine, “Gopher”. This search engine indexed ordinary text documents instead of indexing computer files like “Archie” did. Some of the Gopher sites turned into Web sites and the predecessor of the World Wide Web appeared. In 1993 another search engine was made – “Veronica”. “Veronica” indexed the Gopher documents and brought another improvement: just by typing your request in a search box you could obtain the desired information. The year 1993 offered the first Web search engine and the first robot, “Wandex” or “the lone wanderer”. It was developed at MIT by Matthew Gray. It was used to verify the web growth and, though it took count only of web servers at first, it later considered the URLs also. In a short while, after the “Wandex”, another Web search engine was introduced and its name was “Aliweb”. This search engine didn’t become a huge success because few people understood how they were supposed to use it. It didn’t automatically index the web pages. The pages had to be created by the webmaster and then sent to this Web search engine. It didn’t work out very well because of this.
Somewhere between the years 1993 and 1994, three automatic spiders were created: Jump Station, Repository-Based Software Engineering and the World Wide Web Worm. They were the first to index new found pages by leaping from link to link. These spiders were forerunners or ancestors of the advanced search engine used today. One present well-known search engine is “Yahoo”. It was created in 1994 for web site listing purposes. It was different from others by owning a URL together with the page description. In 1994, the University of Washington was proud to discover that few of their students developed the very first full-text spider, named “WebCrawler”. This invention shortly became very well-known and a model for many search engines to come. In 1995, Eric Selburg developed the “MetaCrawler”, which solved the problem of not being able to use more search engines at the same time. Though, the “MetaCrawler” could simultaneously search different engines such as: “AltaVista”, “Yahoo”, “Excite”, the results took a little longer to be provided.
“AltaVista” was probably the most advanced search engine of its time, before Google appeared, of course. However advanced its options for searching and its use of natural language requests were, Google become more popular and was considered the most used search engine. Created in 1998, Google had some problems in the beginning. Its promotion was a real problem because nobody was interested in the beginning. The solution came fro the advice of David Filo, from Yahoo. A company was made and its success still exists nowadays.
With the help of many years of hard work, our Internet searches are more accurate due to these innovative engines. If you haven’t yet heard of the wonders that the Internet offers, this problem can be solved immediately by using a search engine according to your needs. The amazing thing is that history is continuously made with the help of new creations. People want to make a difference with their own search engine so they strive to improve the existing tools. There might already be another Google out there waiting for you to discover and use it.
