Perhaps you should try some spelling variations:
integration efforts » international efforts, conservation efforts
green innovation » open innovation, gender innovation, model innovation
innovation how » innovation house, innovation _, innovation lab
supply school » supply scheme, survey school
supply shock » supply shocks
supply green » supply urban

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: (( ((supply school) OR (supply shock)) integration efforts. ) OR ( supply green innovation how. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((supply school) OR (supply shock)) integration efforts. ) or ( supply green innovation how. ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((supply school) OR (supply shock)) integration efforts. ) or ( supply green innovation how. ))*.
