Optional, used to build the 'OFFSET n' clause. If not specified results are returned from the first item
available. Note that this parameter must be combined with 'order', otherwise there's no ordering imposed
on the results and subsequent queries may return overlapping data randomly. It's unlikely that this will
actually happen as almost all databases do in fact create an internal ordering, but there's no guarantee
of this (and some operations such as indexing will definitely break this property unless explicitly set).
