Perhaps you should try some spelling variations:
integration efforts » international efforts, conservation efforts
integration schemes » integration schengen, irrigation schemes, integration regimes
die integration » trade integration
support die » support de, support deep, support does
support von » rapport von, support can, support vision
support vs » support _, support a, support 4

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: (( support die integration efforts. ) OR ( ((support von) OR (support vs)) integration schemes. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( support die integration efforts. ) or ( ((support von) OR (support vs)) integration schemes. ))~".
• Adding a wildcard symbol may retrieve word variants: (( support die integration efforts. ) or ( ((support von) OR (support vs)) integration schemes. ))*.
