Perhaps you should try some spelling variations:
"springer finance business model" » "einer finance business model", "merger finance business model", "pardner finance business model"
"springer single business models" » "springer springe business models", "springer eine business models", "springer silke business models", "springer wrangle business models", "springer using business models", "springer sample business models"
"springer simple business models" » "springer silke business models", "springer science business models", "springer sample business models", "springer complex business models", "springer example business models"

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