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