• If you are trying to use Boolean operators, they must be ALL CAPS: (((("springer science business model") OR ((("stronger science using model") OR ("astronomy science using model"))))) OR ((("springer springe business models") OR ("spring spring business models"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"springer science business model\") or (((\"stronger science using model\") or (\"astronomy science using model\"))))) or (((\"springer springe business models\") OR (\"spring spring business models\"))))*".
• Removing quotes may allow a broader search: (((( springer science business model ) or ((( stronger science using model ) or ( astronomy science using model ))))) or ((( springer springe business models ) OR ( spring spring business models ))))*.
