No, it's not solved. Google utterly fails at it. I'm a person with simple needs. I mostly search in English, sometimes in Russian (which is my native language) and sometimes in Japanese (which I'm learning). These languages use completely disjoint sets of characters so it should be obvious to Google what I'm trying to do (since I'm logged in and they know all about me). There's also a setting that allows me to pick languages that Google should prefer when searching (English is always selected). Now there's a little problem: 1) If I choose any language other than English, Google prefers websites in that language over English even if my query is in English. If I'm searching for programming-related stuff, I don't need it poorly translated into my native language, or any other language! I want the original, on the first page of search results. So any language other than English gets switched off. 2) If Japanese is not switched on, Google thinks that any query that consists only from kanji (a subset of Japanese characters that are also used in Chinese) is in Chinese language, so I get pages and pages of Chinese websites before I see any Japanese ones. Since I can't read Chinese at all, it's completely useless. Now, you might say: of course Google has no way to know if I wanted Japanese, not Chinese. Oh, it knows. I can search for a name of a Japanese person, and Google will display a sidebar with their English Wikipedia article, date of birth and nationality and everything, and yet all the search results will still be in Chinese.
