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