[Zope] struggling a bit with querying a catalog

[Henny van der Linde]

This snippet works:

zcat=context.litcatalog
results=zcat({'query' : '/habraken/documenten/dftest','level' : 0})
return results

Can I combine this (path index query) query with a ZCTextIndex with searches
for a certain phrasein a certain field?

If so, can any point to the right syntax?
