predicateWithFormat differs between Tiger and Leopard

I am attempting to search within an SQL database. (coreData)
The predicate below filters the search properly in Leopard, but not in 
Tiger. Have I missed something?

[NSPredicate predicateWithFormat: @"presentation_type == 0 AND (ANY 
toSlides.slide_text LIKE[cd] %@)", [NSString stringWithFormat: @"*
%@*", searchString]]

Thanks,
Rich
