Perhaps you should try some spelling variations:
foreign consent » foreign content, foreign concepts, foreign conquest
forests current » costs current, concepts current, contents current
foreign parent » foreign patent, foreign patents, foreign talent

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: ((((foreign consent) OR (foreign parent))) OR (forests current)).
• Adding a wildcard symbol may retrieve word variants: ((((foreign consent) or (foreign parent))) or (forests current))*.
