[GeoNetwork-devel] Harvester filter syntax

Hi!
I am harvesting a metadata catalogue with the OGC CSW 2.0.2 protocol.
It is working well, but a large number of the records are documents only.
I would like the harvester to filter out those records but cannot find the right syntax.
I have tried to enter a Search filter on Type like this:

!= document
NOT document

but then no records at all are returned.
In the search interface, I can check Documents as Type which gives me the records I do not need.
I would like the harvester to do the opposite.

All hints or suggestions are most welcome.

Regards, Mats.E
