It appears that zcat limits the acquisition of properties to direct children (not XML Document) when indexing. Example: 1) Create afolder with a property named, say, 'city' 2) Create a subfolder (subfolder1) 3) Create a subfolder of that folder (subfolder2) 4) Use ZCat to index the colection: in the expr field enter 'color' Result: The root folder and subfolder1 will be found and indexed, but not subfolder 2. Is this intended?
