ZCatalog doesn't do well on hierarchical searches like this. The way you're doing it (without some sort of change to your objects' structures) is pretty much the only way. There's a "ZTopics" product floating around that is supposed to provide functionality like this, but 1) I don't know if it's released, 2) I've never used it. You *could* add a method to your "superobjects" that returned the meta_type of all of its subobjects and add that to the Catalog index, e.g. def getChildMetaTypes(self): return map(lambda x: getattr(x, 'meta_type'), self.objectValues()) then add getChildMetaTypes as a keyword index... then... for x in Catalog.searchResults(getChildMetaTypes="My Kind Of Object"): ...

(Post #2) I'm trying to search a zCatalog to find all the objects containing a certain type of sub-object.

Right now, I use a dtml-if inside the result loop, but the result count is obviously wrong.

There must be a better way to do this, right?
