Simon Willnauer commented on LUCENE-3862:
-----------------------------------------

I should have been more specific. The reason why I did it that way is that you always have to explicitly downcast if you are sure you are not loosing any precision. If you offer a getShort somebody could accidentally downcast its 64 bit values into a 16 bit values without realizing. However, if it allows us to make similarities generic we need to rething that maybe. 

I kind of like the semantics we have right now ie. you get full 64 bit values no matter what you have encoded.
