Yandex has partnered with Twitter in an agreement that will license the full feed of all public tweets to Yandex's search engine. New tweets will appear in Yandex's Blog Search results in real time.
Yandex will aggregate tweets in Russian, Ukrainian, Belarusian, or Kazakh, as well as top feeds in any other language, and include them in Blog Search results.
Users who initiate a search on Twitter will find the same results at twitter.yandex.ru as in Yandex's Blog Search; users can search by Twitter username or by hashtag. Tweets of more than 2 million users are available for search on Yandex.
