-----------------------------------------------
John, I modified the existing ppd_* tests to run with new configuration on and
off. I copied the queries as they are and did not modify the the statements at
all. If you are keen adding order by to the queries, Will do. I'd like to do in
a follow up and not stop this patch.
> FilterOperator is applied twice with ppd on.
