Perhaps you should try some spelling variations:
detecting covert » detecting over, detecting concept, detecting context
detect novelty » patent novelty, desserts novelty
detect covert » detect concept, detect connect, detect content
detect novel » select novel, detection novel, detecting novel

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((detect novel) OR (((detect novelty) OR (((detect covert) OR (detecting covert)))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((detect novel) or (((detect novelty) or (((detect covert) OR (detecting covert))))))".
• Adding a wildcard symbol may retrieve word variants: ((detect novel) or (((detect novelty) or (((detect covert) OR (detecting covert))))))*.
