> ScrollableResults is trying to load by batches only in forward direction, even if this is the most common use it is trivial to make it a bit smarter.
> This also improves  a "somehow random" loading order, as far as the requested entities are not too far away from each other, or if a "random intelligent" pattern will result in loading all results as end result (and enough memory is available so that caches were not emptied).
