I think if we can we should make all queries fail if they need
positions and they are not there. IMO its illegal to run such a query
on a field without positions. Maybe I miss something but we should be
able to make them fail all the time, right?
While we are on it, would it make sense to move omitTfAP into the
Index enum. It always felt odd that you can omit norms using the enum
but use a setter to omit TF & Pos.
