--------------------------------------------

+1, I reviewed the first patch.

We'll need to fix facet module's dynamic range faceting to skip missing values; I can do this after you commit this patch...

> DocValues should somehow allow a configurable default per-field.
> Possible implementations include setting it on the field in the document or registration of an IndexWriter callback.
> If we don't make the default configurable, then another option is to have DocValues fields keep track of whether a value was indexed for that document or not.
