Yes, it makes sense in this case, it's just confusing because it happens differently in other situations - when doing a normal scroll (not scanning), shards.successful is non-zero even when you've reached the point where there's no more results (and even if you keep going). And if you do a search returning no results, shards.successful is also non-zero.
So, should I ever (not just when scrolling) consider shards.successful=0 to indicate a failure? Or should I ignore it and only look at the shards.failed?
