After you hit enter the upper centre of the screen shows which dictionary/scrabble versions that it's a valid word in. There's a few other filters lower where you can select different dictionaries.
My thoughts are if it's green (valid) in any of the displayed versions then it's a valid word
Edit: Closed examination reveals that they are all official scrabble players dictionaries
