Is Quora a source of information

Search engines have been around since the Internet existed. They are programs that can be used via a browser or mobile via an app. A constant internet connection is important, as the search engine analyzes and evaluates website information and content over the internet. It usually only takes seconds to get a result for a search query. Using a complex and unknown algorithm, the search engine tries to show the user the most relevant result based on the entered search words (keywords). Now you can look at your search results in a ranking list and decide which website you want to go to. The aim of search engines is to present the user with the desired result, but since this is not always the case, the algorithms used have to be continuously developed.

Search engine market shares in Germany: February 2016, source:


The biggest search engine is of course Google, with a market share of approx. 95% in Germany. Then follow Bing, the search engine from Windows with a market share of approx. 4% and Yahoo with a market share of less than 1%.

Other search engines are e.g. T-Online,, AOL Search,, GMX or However, only Google and Bing have their own search algorithm - all other search engines are based on it. There are also special search engines that focus on a certain target group, such as fragFinn, the search engine for children with child-friendly search results. Some others rely on anonymity, such as at or DuckDuckGo. They advertise that they attach particular importance to the data protection of the users.

Google can hardly be beaten worldwide, but there are individual countries where other search engines are ahead. In China that is, one of the top five most viewed websites in the world and in Russia Yandexwho have a market share of approx. 60% there.


The Internet offers freely accessible information on every subject to an ever increasing extent. The challenge of finding the information you are looking for quickly and in a targeted manner within this unmanageable flood of information increases. At the same time, as a website operator, you want to be found quickly and easily in order to bring your online offer to your target group. Search aids are available to help you master this gigantic amount of data on the Internet. Search engines in particular have established themselves as a means of research. We present the history of the search engines in a chronological overview below.

Archie was born by Alan Emtage at McGill University of Montreal. The program searched for FTP servers and collected their files. This allowed users to search the index for file and directory names. Because of his complex service, Archie didn't get through.

Veronica was the largest search index for the Gopherspace, an information space that all publicly accessible Gopher servers in the world displayed together. The program was developed at the University of Las Vegas. Veronica is short for V.ery E.asy R.odent Oriented Net-Wide I.ndex to C.omputerized A.rchives. Using the search engine was relatively easy. Search terms could be entered, for which appropriate documents were then determined in the Veronica database that contained the term in the title. Gopher, on which Veronica was based, ultimately died of charging for commercial use. That was the end of Veronica too.

The Wanderer was the first real WWW crawler, that is, its job was to capture the web. Originally, however, he only counted the servers on the web. The Wanderer was developed by Matthew Gray at MIT. The project was discontinued in 1995.

Michael L. Mauldin, who later also developed the search engine "Lycos", started the Wandex program in 1993. Wandex collected URLs and archived them. This enabled the data collected to be searched.


In October Aliweb (A.archive-L.ike I.ndexing of the Web) developed. Operators of WWW servers must store a description of their service in a standard file format. The address of this file was sent to the program. Later in the year the search engines Jumpstation, WorldWideWeb and Worm went online. They were robots that indexed websites by title and URL. All of them have since stopped working.

The search engine WebCrawler by the student Brian Pinkerton is put online. WebCrawler was the first full-text search engine and contained around 4000 documents. The search engine arose from desktop software. In 1995 WebCrawler was sold to AOL and in 1996 by AOL to Excite.

In July of that year, Lyocs was put online by Michael L. Mauldin, who had tried Wandex a year earlier. Lycos had a somewhat more complex ranking algorithm and considered the proximity of search terms to one another. The word frequency within a page was also evaluated.

David Filo and Jerry Yang from Stanford University are starting a kind of web catalog, in other words a collection of their best Internet addresses under the name Yahoo!

Architext was developed by six students at Stanford University. The search engine was later renamed Excite.

AltaVista was developed by Louis Monier, Joella Paquette and Paul Flaherty in a non-university setting. The search engine emerged from a research project by the Digital Equipment Corporation (DEC). With AltaVista it was possible to carry out a full text search for relevant pages on the web.

Infoseek was developed by Steven Kirsch from MIT. The search engine allowed relatively complex Boolean operations.

Hotbot skated very well. It allowed a search in the search results and used the technology of Inktomi and later DirectHit. At the end of the 90s, Hotbot AltaVista overtook the rank.

Inktomi was developed by Eric Brewer and Paul Gauthier of UC Berkeley. Inktomi supplied its search technology to many other search companies. The name comes from a legend of the Lakota Indians about a spider that was smarter than its larger conspecifics.

Ask Jeeves was developed by Garret Gruener and David Warthon, also from UC Berkeley. With this search engine, the search was entered in the form of questions in full sentences. The name is derived from a character in a novel - Jeeves the butler.

1998 was the birth of the most successful search engine - Google. It was developed by Larry Page and Sergey Brin from Stanford University. What is special about Google is that it uses links as a basis for evaluating the ranking. The PageRank algorithm is developed in which documents are rated and weighted based on their link structure. Until 2005, Google only recorded documents up to 101 KB.

DirectHit introduced click popularity, which means that users' clicks were considered a ranking factor. The search engine was based on Hotbot's technology.

GoTo was best known for selling placements. The search engine took up the concept of Open Text from 1996. The higher the bid, the higher the ranking. The purchased results were delivered to many other portals and search engines from 2000 onwards. GoTo was later renamed Overture and sold to Yahoo in 2003.

Teoma was founded by Apostolos Gerasoulis and his colleagues at Rutgers University in New Yersey. Back then, the search engine was highly regarded as a competitor to Google. Teoma developed a new way of evaluating links. Later it was taken over by Ask Jeeves. Today, search results are based on Teoma's algorithmic search technology.

In 2004 MSN Search started as a beta version. In addition to the text search, the MSN search offers an image and message search. Later on, MSN Search was also known as Live Search.

Microsoft's Bing search engine is the successor to Live Search. In contrast to the simple design of Google, the start page of the search engine has a background image that changes daily. The US version has most of the functions that are less common in other countries, such as a separate search bar with data from Facebook, Twitter, Quora, Foursquare, LinedIn, Google+ & Co.
