Perhaps you should try some spelling variations:
"stronger science business model" » "springer science business model", "stronger evidence business model", "stronger stance business model", "stronger service business model", "stronger science business models"
"stronger finance business model" » "stronger guidance business model", "stronger stance business model", "stronger evidence business model", "stronger finance business models"
"bigger science using model" » "big science using model", "river science using model", "better science using model", "bigger science ising model", "bigger science using mobile"

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