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