IIRC, the catalog-aware zclasses are indexed automagically when created, but not properties you set after creation. So when you search for track_hasfile='on' , Zcatalog doesn't have that property indexed: You'll have to add : <dtml-call reindex_object> in your Zclass Constructor method ( if you change properties there) like this : <dtml-with "Zclass_name.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "propertysheets.Propertyshhet_name.manage_editProperties(REQUEST)"> <dtml-call reindex_object> </dtml-with> - Another possibility could be that you haven't added track_hasfile to your indexes in Zcatalog. If it is just a on/off-flag (which it looks like from here) , add it as a field-index..
