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