Duckduckgo uses Yandex crawlers.

That explains why Yandex keeps crawling pages that it can't index! (For those who have never checked it out: Yandex's wmt includes a breakdown of why various pages aren't indexed. One category is "unsupported language".) Yup, there they are on DuckDuckGo.
DuckDuckGo also has an interestingly different way of handling queries in languages it doesn't know. I tried two unrelated languages in two unrelated scripts and saw the same technique at play each time. Not an approach I'd recommend, but definitely an alternative to g###'s exact-match-or-nothing approach.
