Retrieves the previous page of query results.
The prev() function retrieves the previous page of query results.
The page size is defined by the limit()
function, can be retrieved using the pageSize property, and
navigating through pages is done with the prev() and
next() functions.
If items are added or removed between calls to prev() the values returned
may change.
