Some search engines do an excellent job of searching for specific sites, while others, on the contrary, perfectly search for the necessary information, so the search engine must be chosen precisely depending on the task.
Most Web users, by virtue of habit, use one search, without even suspecting that the various Internet search engines are very extensive, have their own specific features, by virtue of which each system can be assigned a specific type of search task.
What are the search engines of the Internet, a list of search tasks between which is traditionally divided and what is the history of their occurrence and development?
The first search engines appeared at the time of the formation of the Internet - then there were few computers connected to the Network, and all of them were used for purely scientific purposes. It was at that very time, that is, even before the development of the World Wide Web, that the very first search tool called Archie was developed.
At the next stages of the development of the Network, many tools for searching for information appeared and disappeared, and only a few of them survived to the present day, and already units became popular and reached the status of a solid and respected brand in the world.
All search engines have their own constantly changing and improving algorithms, which are used to calculate page rank. But it is characteristic of all search engines that they take into account link popularity or the so-called citation index of resources to one degree or another.
The most popular search engines in the Russian segment of the Internet are Google, which is considered a kind of universal search standard. As the main criterion for ranking sites, Google uses the PR index (Page Rank), which is calculated using a special patented formula. The index depends not only on the number of referring sites, but also on their own “weight”. Google provides many additional features for both ordinary users and webmasters and optimizers.
Among the Russian-speaking search engines Yandex is considered the undisputed leader. With it, you can search the web for information in several languages. Its characteristic feature is the ability to index documents in various formats - doc, rtf, pdf, txt and others. Yandex uses the so-called TIC (Thematic Citation Index), which depends on the number of external links to the site, as a ranking criterion. Yandex has many additional features, including news feed, weather widgets, electronic money, as well as many tools for the webmaster.
