AW: AW: [Zope] Searching the Catalog

[Marc Fischer]

Hi,

<dtml-in "Catalog(Titel='hello', Vorschau='World')" size=50
start=query_start>

works fine. But with the OR search a get some trouble. If I try:

<dtml-in "Catalog(Titel='hello') + Catalog(Vorschau='world')" size=50
start=query_start>

.. I get the message:

Error Type: TypeError
Error Value:__add__nor_radd__defined for these operands

Someone an idea??

Marc
