You may be able to get more results by adjusting your search query.

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