> Just like term vectors before it, it has a O(n) seek-by-term. 
> But this one also advertises a seek-by-ord, only this is also O(n).
> This could cause e.g. checkindex to be very slow, because if termsenum supports ord it
does a bunch of seeking tests. (Another solution would be to leave it, and add a boolean so
checkindex never does seeking tests for term vectors, only real fields).
> However, I think its also kinda a trap, in my opinion if seek-by-ord is supported anywhere,
you kinda expect it to be faster than linear time...?
