Perhaps you should try some spelling variations:
structural functionalization » structure functionalization, structural functionality, structural regionalization
structural functionalized » structural functionality, structural functional, structure functionality
"structural functionalism" » "structural functional", "structural functions", "structure functional"

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: (("structural functionalism") OR ("((structural functionalized) OR (structural functionalization))")).
• Removing quotes may allow a broader search: (( structural functionalism ) or ( ((structural functionalized) OR (structural functionalization)) )).
• Adding a wildcard symbol may retrieve word variants: (("structural functionalism") or ("((structural functionalized) OR (structural functionalization))"))*.
