Yes, I am.

string = <Briggel Braggel> (without the "<>")
predicateFormatContent = @"kMDItemTextContent like %@";
predicate = <kMDItemTextContent LIKE "Briggel Braggel">
finds "Briggel and Braggel". Bad

string = <"Briggel Braggel"> (Note:  " part of string)
predicateFormatContent = @"kMDItemTextContent like %@";
predicate = <kMDItemTextContent LIKE "\"Briggel Braggel\"">
also finds "Briggel and Braggel". Bad

string = anything
predicateFormatContent = @"kMDItemTextContent like \"%@\"";    or:
predicateFormatContent = @"kMDItemTextContent like \'%@\'";    or:
predicateFormatContent = @"kMDItemTextContent like '%@'";    
predicate = <kMDItemTextContent LIKE "%@">
finds nothing. Also not good. (There are lots of files containing %@ 
though).

string = <'Briggel Braggel'> (Note:  ' part of string)
predicateFormatContent = @"kMDItemTextContent like %@";
predicate = <kMDItemTextContent LIKE "'Briggel Braggel'">
finds nothing. Still bad.

Now I do not have any more ideas.
Anyone else? Finding a string containing blanks on Tiger?

Kind regards,

Gerriet.
