Perhaps you should try some spelling variations:
"spider bridging business model" » "spider building business model", "spider driving business model", "spider doing business model", "video bridging business model", "fiber bridging business model", "guide bridging business model", "spider bridging business models"
"driven science business model" » "driven finance business model", "driven service business model", "driven science using model", "driven science 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: (("driven science business model") OR ("spider bridging business model"))*.
• Removing quotes may allow a broader search: (( driven science business model ) or ( spider bridging business model ))*.
