Hi!
I spent today looking at identifying and converting queries typed on the wrong keyboard on the English and Russian Wikipedias.
That's a great idea to address that. I do it all the time :) Though, I use different keyboard лаыоут ("phonetic"[1] one, not "йцукен" [2] one) but that's because I write most of the time in English. People that write most of the time in Russian would probably use the traditional Russian one [2].

Interestingly enough, google when you search for дштгч (linux) does search for Linux, but duckduckgo not only searches for Linux but also presents as a first result Linux page of Russian wikipedia! I think it's pretty smart.
P.S. both google and ddg know to handle уoutube (with cyrillic first letter) too.
