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