> I think the approach in 3.x for handling un-valued docs, and making it
> possible to specify how such docs are sorted, is better than the
> solution we have in trunk.
> I like that FC has a dedicated method to get the Bits for docs with field
> -- easy for apps to directly use.  And I like that the
> bits have their own entry in the FC.
> One downside is that it's 2 passes to get values and valid bits, but
> I think we can fix this by passing optional bool to FC.getXXX methods
> indicating you want the bits, and the populate the FC entry for the
> missing bits as well.  (We can do that for 3.x and trunk). Then it's
> single pass.
