• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("springer finance business model") OR ("specter finance business model"))) OR ("springer science using model"))) OR ("springer wrangle business models"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"springer finance business model\") OR (\"specter finance business model\"))) or (\"springer science using model\"))) or (\"springer wrangle business models\"))*".
• Removing quotes may allow a broader search: (((((( springer finance business model ) OR ( specter finance business model ))) or ( springer science using model ))) or ( springer wrangle business models ))*.
