I think that something is also correct in this sentence. Is it so? Is there a difference of meaning between something and anything in this sentence?
You usually use something in affirmative and anything in negative or interrogative sentences
Thank you, I got it.
does he know something and does he know anything are different questions. the Ukrainian one may mean either, you distinguish by intonation.
something should also be correct as well. Without more context it can be understood as anything or something
