• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"springer science business model\") or (((((\"springer bridge business model\") OR (\"sprinkle 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 ( sprinkle 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 ("sprinkle bridge business model"))) or ("springer bridge business models"))))*.
