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