Hi Cliff,

I know this is not exactly what you are trying to do, but in similar =
situations I =C2=AB normalize =C2=BB keys before emitting them =
(transforming =C2=AB =C5=A0 =C2=BB and =C2=AB s =C2=BB into =C2=AB S =C2=BB=
 for example). You can still get the original (unnormalized) words in =
the `doc` or `value` field. Even if =C2=AB S*** =C2=BB, =C2=AB s*** =C2=BB=
 and =C2=AB =C5=A0*** =C2=BB will not be sorted *for real*, they will be =
next to each other in the sorted list.

Implementation is trivial but here is an implementation:=20
