When you create a dimension, it will sort the data for you using a dual-pivot quick sort algorithm. Calling dimension.top(n) will return you the top documents back. Vice versa, calling dimension.bottom(n), will return you the bottom most documents. It will be the natural sort order, so if you want all the documents back sorted descending, use:

var sortedDescending = dimension.top(Number.POSITIVE_INFINITY);
