How to query that a collection does NOT contain something?

[WT]

I have a persisted class "O" that holds a Collection of Strings.  How do I query for all object of class "O" that do NOT have a specific String in their collection?

I searched for 1 hr and could not find the answer.

How would you do in native SQL?

Have you tried

query.from(O).where(O.tragetCollection.contains("String I want").not());

?
