As part of the Vega update, Yandex introduced Yandex.Q, a new question-and-answer service.
Yandex.Q makes use of the Yandex.Experts tool, which was introduced in the 2018 Andromeda update, and TheQuestion, a Q&A forum acquired by Yandex in early 2019 to form the new service.
Yandex.Q contains more than one million questions and answers from a gamut of subject matter experts. Users will type questions as normal in the Yandex.ru search bar, and Q answers will appear at the top of search results (akin to featured snippets in Google). The example given by Yandex in the Vega blog post is:
For example, someone looking for information on Alexander Pushkin can see answers from a literary critic, or a search on the behaviors of seals will result in a response from the head of the National Arctic and Antarctic Museum.
