Does the content you're looking for exist in your language, and if so, can you find it on some other search engine? It seems like a lot of 'knowledge forums' are in English.
Indeed it does. These are mostly queries for non-computer stuff, like I'm interested what's difference between various variants of pepper sprays, or merits of oil vs oil-less air compressor, etc. All the queries I can think of that would have Wikipedia page at the top in the english version give me only eshops and blogspam from sellers in my local language.
