The history of search engines is the story of university students' projects to develop into commercial enterprises and revolutionizi
ng the field as they went. The first attempt at creating a search engine called Archie and it was created in 1990 by Alan Emtage a student at
The next evolutionary step in search engine was the introduction of "bots". The first use of robotic technology was in the search engine World Wide Web Wanderer. Simply, what robots will do is scan the Internet for URL's that start at the same place and using the links in the previous site to find more places. The problems with these first robots was that if they were not written correctly, they would create too many hits on a server rotten system performance.
To combat these initial problems Martjin Koster came out with the first web directory called "Aliweb" in October 1993. Web directories are different than search engines because the sites listed in them are not from the robots, but rather from human editors reviewing sites and place them in the library.
But shortly after, in December 1993 a new robot was born. This was called "spider". Spiders added a much wider degree of accuracy by indexing the entire text of a webpage. The older robots only indexed URLs and titles on one side, which meant that some relevant keywords could not be indexed. This greatly improved relevance ranking of their results, and thus was the first major step to form the major search engines as we all become so accustomed to using today.
Not long after the spider, so we are the emergence of some big guns. In 1994 came out of
At this point there are two different types of search engines, "author controlled" such as Altavista and Excite, where the results were ranked by keyword relevancy, and "editor controlled" such as Yahoo, where people are placed manually websites in their index.
Then in late 1997 from
Search engines have had an enormous influence on American life. They basically will give you a little about what information you want, you have to do is type in the search box the item you want to learn more about. Humans are natural born information junkies, we always want to know more and find out more and search engines has made this desire of our extremely easy to cure. Think about it, maybe you need to create a simple problem you have with your car. By using a search engine to do some research, you can very easily figure out the problem, saving you a very expensive trip to the car repair shop. They are great teaching tools, before search engines emerged, if you really wanted to learn something, you will go to your library and check out a book. Now, before making the trip, you can find out what you would by just sitting at your desk and surfing through Google. The list goes on about the many benefits of this great new technology we call search engine. We are sure you can remember a time when you've found some very good information by using a. If you're anything like us and find yourself addicted to this easily accessible information highway then your use of them daily.
Search engines by nature were made very easy to use. But with a little extra knowledge about how they work you can really benefit from them and find great information very quickly. With the right knowledge about search engine and use of specialized tools, you can literally find anything you want. And when we mean something, we mean anything. For us personally we're excited to see what search engines will evolve in future. The sky is the limit. Who knows what type of search spiders will spawn future, but one thing is certain there will be newer and newer search technology it's just our human nature to keep trying to top ourselves.
