MOSCOW - Russia's top search engine Yandex said Tuesday it has teamed up with Twitter to allow the Russian firm to show the full feed of all public Twitter posts.

The deal will give it full access to all tweets except for private ones, New York-listed Yandex said in a statement.

It will also allow the Moscow-based company "to improve the quality of the search," and users will be able to find tweets "just moments after they have appeared," said Anton Pavlov, Yandex's blog search manager.

Twitter posts will appear both in a blog search and on a separate website, twitter.yandex.ru.

Terms of the deal were not disclosed.

Yandex's Twitter deal highlights the increasing importance of microblogging as a source of information.

Yandex is Russia's largest search engine, occupying some 63 per cent of the market. Google trails behind with a 23-per cent share.

Google and Twitter last year failed to renew a deal for the search giant to include Twitter results in its feed.
