Perhaps you should try some spelling variations:
"stronger evidence business model" » "stronger science business model", "stronger silence business model", "stronger resilience business model", "strong evidence business model", "stronger evidence business models"
"springer service using model" » "springs service using model", "springer series using model", "spring services using model", "springer services using model", "springer service ising model", "springer service using mobile"
"springer serie using model" » "springer series using model", "springer marie using model", "springer springe using model", "springer serie ising model", "springer serie using mobile", "springer serif using model", "springer serve using model"

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