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