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