NSPredicate: To be, or not to be

When I use an NSMetadataQuery with the NSPredicate 
<kMDItemTextContent LIKE "To be, or not to be;"> it seems to find all 
documents which contain these words in any order; and as they are 
kind of common, it finds 23363 files.

Not quite what I intended.
Actually I am looking for those documents which contain this string 
exactly as written (e.g. Shakespeare/Plays/Hamlet/3.1.rtf ).

So: how do I have to rephrase my NSPredicate?
And, no: <kMDItemTextContent LIKE "The slings and arrows of 
outrageous fortune"> is not the answer to my question.

Kind regards,

Gerriet.
