[Zope] problem with querying a catalog

[Henny van der Linde]

Hi,

I have some trouble querying  a catalog.

This DTML works. It get's only the edf objects in the path.

<dtml-in expr="dfcatalog(meta_type='edf',

path='/avin/literatuur/antroposofische_literatuur/artikelendatabase/ms')">
        <a href="&dtml-absolute_url;"><dtml-var title></a>
</dtml-in>

This Python script doesn't work. It returns ALL the edf objects on the site.

zcat=container.dfcatalog
results=zcat({'query' :
'/avin/literatuur/antroposofische_literatuur/artikelendatabase/ms','meta_typ
e':'edf'})

Thoughts?
