How Yandex search results work
Posted: Sun Feb 02, 2025 8:08 am
However, no one knows the full list of criteria used, so when promoting, optimizers have to rely on their own experience and intuition. And since all algorithms are regularly updated, it is simply impossible to invent a promotion method that would work without misfires.
Currently, Yandex knows several trillion addresses. Every day, about two billion of them are analyzed. Sites are processed by spider robots, crawlers. They go to the page, study its contents, make a copy, and then start following the links. In this way, the system receives information about what information is on this site. After that, the indexing process begins.
By simple calculations, it can be found out that crawlers will analyze all currently known sites in about two years. However, in reality, the work on creating a search base will continue after optometrist accurate email list that, since during this time a huge number of new addresses will appear.

Determining the index of a site is the process of collecting basic data about a resource, including language, keywords, and outgoing links. It is also worth mentioning a tool such as Yandex logs, which are actively used in indexing and ranking. Its purpose is to take into account the behavior of users: which links in search results they open and which they do not. All the collected information helps to set the site index.
Once the search indexes are defined, they are sent to the database. Yandex has it on the MapReduce YT platform. Here, the data is stored in the form of files, the total volume of which currently amounts to about 50 petabytes, or 50 thousand terabytes.
Once a week, an update occurs, that is, a search base update. At this time, the information that was collected and analyzed by robots for the previous period is added to the search and becomes available to users. By the way, Igor Ashmanov, a specialist in the field of IT and software development, claims that in terms of the volume of the information base, Yandex surpasses Google, and several times.
As you can see, indexing is a long process and occurs in parallel for a large number of different data. However, some files are analyzed and made publicly available faster than others. This happens, for example, with news, because in this area the whole point of publications is their urgency.
Queries entered into Yandex are implemented as follows (balancers here are the machines that generate the results):

The output is formed from the results of three average metasearches. This means that for each keyword the system outputs relevant pages, images and videos. This happens because the request goes through three different indexes. Using them, it goes down to the very depths of the search base, divided into several thousand parts. This process is called search clustering.
Clustering requires software that performs countless different tasks. Naturally, each program also has certain system requirements and takes up quite a lot of space. Therefore, search clustering also requires a huge amount of computer hardware hosting.
Storage and transfer of software and the data required for it in Yandex occurs through an internal torrent tracker. It is noteworthy that in terms of the number of distributions it is ahead of even the world's largest pirate tracker The Pirate Bay.
