Yandex checks all search queries for typos and other mistakes. This system highlights and corrects mistakes in phrases and individual words, it can even recognize and correct text that has been accidentally entered in the wrong keyboard language.
If our typo correction system detects a typo, for which it is very likely that the correct version is known, for example the word 'brakfast' will automatically be corrected, and the search results page for the corrected version 'breakfast' will be automatically displayed.
The degree of accuracy depends on many factors, the most important of which is the number of users confirming our suggested version.
If it appears to you that our version is incorrect, and you would like to view the results for the original (uncorrected) search, follow the link in the message “The query <...>; has been corrected.”, which is located just below the search bar.
