Perhaps you should try some spelling variations:
european federation » european integration
europe's migration » europe migration, europe emigration, european immigration
european migration » european integration
prophet's mission » europe's mission
european emission » european commission, european dimension, european expansion

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: ((prophet's mission) OR (((european emission) OR (((europe's migration) OR (((european migration) OR (european federation)))))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((prophet's mission) or (((european emission) or (((europe's migration) or (((european migration) OR (european federation))))))))".
• Adding a wildcard symbol may retrieve word variants: ((prophet's mission) or (((european emission) or (((europe's migration) or (((european migration) OR (european federation))))))))*.
