• If you are trying to use Boolean operators, they must be ALL CAPS: ((((springer springe) OR (river science))) OR (stronger science)) ((((business mit) OR (business man))) OR (business model)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((springer springe) or (river science))) or (stronger science)) ((((business mit) OR (business man))) or (business model))".
• Adding a wildcard symbol may retrieve word variants: ((((springer springe) or (river science))) or (stronger science)) ((((business mit) OR (business man))) or (business model))*.
