• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"springer science business model\") or (((\"stronger science using model\") OR (\"stronger science using mobile\"))))) or (\"springer price business models\"))".
• Removing quotes may allow a broader search: (((( springer science business model ) or ((( stronger science using model ) OR ( stronger science using mobile ))))) or ( springer price business models )).
• Adding a wildcard symbol may retrieve word variants: (((("springer science business model") or ((("stronger science using model") OR ("stronger science using mobile"))))) or ("springer price business models"))*.
