The Internet has firmly entered into the life of almost every modern person. It is already difficult for people to imagine how it was possible to do without this huge storehouse of information in which you can gather so much useful and entertaining. The global network has become not only a place where you can find answers to all the questions but also a way of communicating, interacting with other people. With the help of a computer network every person, today can get an education, find a job, establish a personal life, in general, become a full-fledged member of society.
People skillfully use the provided benefits of civilization, sometimes without hesitation, exactly how they work. It is unlikely that there will be at least one user on the Internet, which does not use search engines to retrieve information. To date, many search engines are competing for the right to be called the best.
Internet search engines
Google’s monopoly has no end, it is also characteristic of the CIS, in particular, the segment of the Internet. In the US, 64.5% of queries are performed through this search engine. Yes, and smartphones on Android with the appropriate browser, even more, help the spread of Google.
Alternatively, Google does exist, but not the same as in the post-Soviet space in the face of Yandex or Rambler. For example, the second most popular Bing system, created in 2009 by Microsoft, occupies only 16% of the search market. However, it has some advantages, for example, it more often offers to autocomplete, provides a conveniently designed list of videos that are loaded faster. Advanced image search allows you to understand user requests better and exclude duplicate images.
Also, this system since 2011 owns Yahoo – one of the most popular search engines in the world, but mainly due to the e-mail service. Both systems occupy about 33% of the share of the Western Internet.
As you know, the biggest search engines like Google, Bing and Yahoo are often accused of collecting user data. Therefore, interest in the DuckDuckGo system (DDG) increases, which does not save them, does not track your location and does not produce search results depending on the user’s preferences. That is, you remain anonymous. On the right, at the top, is the system’s key phrase: “We do not track you”. The search engine is made on free code, and the most curious is that it is a commercial partner of Yandex, as the link at the bottom of “In partnership with Yandex” says.
3% of search requests are accounted for by the search system Ask.com, which used to be called Ask Jeeves. The peculiarity of the site is that it functions in the “question-answer” format, and the answers are sent by users. By quality, it is much inferior to the more famous search engines.
Types of search engines
There are four types of search engines: with search robots, man-driven, hybrid and meta-systems.
- The system using search robots
They consist of three parts: the crawler (“bot”, “robot” or “spider”), the index and software of the search engine. The crawler is needed to bypass the network and create lists of web pages. Index – an extensive archive of copies of web pages. The purpose of the software is to evaluate the search results. Because the search robot in this mechanism regularly explores the network, the information is more relevant. Most modern search engines are systems of this type.
- human-managed systems (resource catalogs)
These search engines get lists of web pages. The directory contains the address, title and brief description of the site. The resource directory looks for results only from the descriptions of the page submitted to it by the webmasters. The advantage of directories is that all resources are manually checked, hence, the quality of the content will be better than the results obtained by the first type system automatically. But there is also a drawback – the updating of directory data is done manually and can significantly lag behind the actual state of affairs. The page ranking cannot be instantly changed. Examples of such systems include the directory of Yahoo [en], Dmoz and Galaxy.
- hybrid systems
Such search engines as Yahoo, Google, MSN, combine the functions of systems using search robots, and systems controlled by humans.
Metasearch systems combine and rank the results of several search engines. These search engines were useful when each search engine had a unique index, and the search engines were less “smart”. Since now the search has improved much, the need for them has decreased. Examples: MetaCrawler [en] and MSN Search.
Alternative search engines
The system AOL Search Engine since 2005, partially (5%) is built into Google, the peak of its popularity came in the late 90’s, after which it was no longer actively used. The system has no own database, ODP and Inktomi search results are used.
Speaking about foreign search engines, one should not forget about the Chinese web service baidu.com, which due to the availability of the Japanese version is in second place in the number of processed requests – 18.03% of the global search share, which is more than Bing. He has his online encyclopedia, which is more popular than Chinese Wikipedia, and an antivirus program.
If you ever used the Internet Explorer browser, you probably noticed the MyWebSearch toolbar, which is built in automatically. It can also appear as a result of installing free programs, which is highly undesirable because it is not so easy to remove it. Nevertheless, every month the site is visited by approximately 60 million people (Ask – 145 million, DDG – 13 million).
It is a system for sharing knowledge, where the erudite community offers answers to questions. The response rate of each user varies depending on the ratings of other visitors. Reminds social network, integrated with Google and Facebook.
