So eventually I discovered that this question has a history. Back in 2008 Keary and Garriet discussed this:
http://webcache.googleusercontent.com/search?q=cache:HXWdzJeGeDcJ:www.cocoabuilder.com/archive/cocoa/208612-nspredicate-containing-contains.html+&cd=4&hl=th&ct=clnk&gl=th&client=safari Alas, none of that worked for me, but that’s exactly the same problem as described. I also found some history of it on SO, but I don’t understand the “solution” - which the asker confusingly says “I marking this as the solution even though it doesn’t answer my question because my question was misleading”. http://stackoverflow.com/questions/11476466/use-an-nspredicate-to-detect-not-contains I’ve tried all the %K and so on options. I’ve actually even downloaded Xcode 4 and built a test project in 10.7 Lion so I could debug it directly. Always the same error: “Unknown type of NSComparisonPredicate given to NSMetadataQuery”. LIKE works, but as I said doesn’t give me the right results. MATCHES fails, as does CONTAINS. I’m beginning to think this is a bug in NSMetadataQuery.
