Hi, I have a Product class ( OrderedFolder, PropertyManager ) which adds a zCatalog(id = 'Catalog' ) when it is created. A batch process uploads a file which contains the data to add objects of class tPatient( CatalogAware, OrderedFolder, PropertyManager ). Catalog has a fieldIndex on 'surname'. After the upload the patients appear in the Catalog but the ZSearchInterface form will not return any results. Search on null input produces all the tPatients. If I edit a tPatient instance, the search interface will then return the correct patient thru the SearchInterface form. The tPatient.editPatient method calls self.reindex_object(). Have tried deleting and creating Catalog by hand and looking at ZCatalog.py to no avail. David
