• If you are trying to use Boolean operators, they must be ALL CAPS: (("laser science business model") OR ((("springer bridging business model") OR ("springer bridging business models")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"laser science business model\") or (((\"springer bridging business model\") OR (\"springer bridging business models\"))))".
• Removing quotes may allow a broader search: (( laser science business model ) or ((( springer bridging business model ) OR ( springer bridging business models )))).
• Adding a wildcard symbol may retrieve word variants: (("laser science business model") or ((("springer bridging business model") OR ("springer bridging business models"))))*.
