Twitter has signed an agreement with Yandex, Russia's leading search engine, that will see tweets show up in search results "in a matter of moments." As with Twitter's deal with Bing, the agreement with Yandex licenses the full feed of public tweets, and search results will include tweets in Russian, Ukrainian, Belarusian, and Kazakh, as well as top tweets in other languages. Users can also search by both username and hashtags, and Yandex has launched a Twitter-specific search engine to go along with its standard search.
Yandex is currently the most popular search engine in Russia, with more than 60 percent market share, and has operations in the Ukraine, Kazakhstan, Belarus, and Turkey, in addition to Russia. With deals in place with both Yandex and Bing, Twitter appears to be making up for its now-defunct arrangement with Google, which ended last summer. Since then Google has integrated Google+ into search results — something Twitter wasn't too happy about.
