Binaries in Snow Leopard reveal kMDItemFSCreatorCode in only two pieces of active code:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/Metadata .framework/Versions/A/Metadata
/System/Library/PrivateFrameworks/SpotlightIndex.framework/Versions/A/SpotlightI ndex
But kMDItemFSCreatorCode itself appears to have been deprecated as a metadata attribute. (Or perhaps it was never fully implemented. I don't find it listed in Apple's metadata reference guides going back to Tiger.) Scanning through the various .lproj files in /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/Metadat a.framework/Versions/A/Resources/ does not reveal any mappings in the schema.strings files where I would expect to find kMDItemFSCreatorCode listed for a metadata attribute that Apple continues to support. Nonetheless, vestiges of the code that makes the Raw Query/kMDItemFSCreatorCode search work still live in Snow Leopard binaries.
Presumably Apple engineers believe that kMDItemCreator will serve adequately into the future. Perhaps, but first there's a lot of clean-up work to do on the past before making the transition.
@fruhulda--I switched to Swedish on a clone drive and the Raw Query worked for me (no translation needed). Perhaps the difference is that I originally installed the OS in English and therefore can access kMDItemFSCreatorCode in a Raw Query in any language. But honestly, I don't really know.
@ChangeAgent--Glad to hear it's working.
