Why would they be searching in English? Also those numbers are "relative popularity" on a scale of 0-100. I'm seeing what the article claims here, more or less. But it's a little unclear exactly what search terms they were all checking.
Good point, here's the Russian translation of "how to leave Russia", which doesn't appear to be much different than the English version.

EDIT>> This is wrong! My mistake, when I translated, I accidentally switched the source country back to USA.
