Language search options?


I saw in advance search options that i can tell twitter language for my search results, i was wondering if it’s possible to use negative prefix for languages ?
I am from Serbia, and i need tweets from Serbia, Bosnia etc… but keywords return many english tweets is it possible to tell to twitter that i want tweets that match keywrods and are not in english, spansih, arabin, german ?

something like notlnag:en,es ?



Did anyone managed to do this ? Is this even possible ?
