Now, "голосование на пеньках" (voting on stomps) is a mockery of Putin's constitution referendum by opposition. When searching this phrase in Google the front page is again Putin controlled media: tass, rbc, kommersant, rg.
Yandex apart from the aforementioned web-sites has US State Department / Soros funded meduza and svoboda.org, liberal (in American sense) tjournal, Deutsche Welle.
It seems Yandex gives preference to the most relevant sites when Google decides what's good ("credible") for you.
