If you are aware of it, that's about all you need to know. What is said of
the horizontal dataset refinement behavior tells you everything else you
need to know.

You simply add it as an attribute to your ordering links entries.

I recommend that you always use POS=0 which simply turns the feature on. You
can go greater than zero if you want refinement to occur on an nth character
when incremental searching. This is the only other area where a POS greater
than 0 should be considered.
