Translate API V2: error "Bad language pair: {0}"

[golubev]

Hi.
For some requests I get the response:

{
"error": {
"errors": [
{
"domain": "global",
"reason": "badRequest",
"message": "Bad language pair: {0}"
}
],
"code": 400,
"message": "Bad language pair: {0}"
}
}


Request for example:

https://www.googleapis.com/language/translate/v2?key=<MY_KEY>&target=en&q=%D0%A5%D0%BE%D1%87%D1%83%20%D0%BD%D0%B0%D0%B9%D1%82%D0%B8

(I try to translate russian words "Хочу найти")

Why this error happen?

I am wondering if, for some reason, it's failing to detect the language as Russian. See what happens when you add &source=ru to your url.

Yes, when add "&source=ru" to url request completes successfully. But
language detecting don't work correctly? It is an error in API?

I suspect there's just not enough text there for detect to work right. It really struggles with short strings and/or random words bunched together. I would suggest specifying the language if possible and/or sending actual phrases that are no less than three words in length. In my experimentation over the years, it was at about three words that you can start to trust the detection and translation.
