You can't filter on null values.
The reason for that is because ThriftDB sets attribute values to null
by default so null values are effectively undefined. The logic behind
that has to do with ThriftDB's flexible schema. I'd be happy to go
into more detail about that if you're interested.
One way around this is to treat empty urls as empty strings instead of
None. ThriftDB indexes everything that isn't null so you should be
able to filter on an empty string. I'm somewhat swamped so let me know
what the priority level is for that?
