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

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 functional"))) OR ("structure functions"))) OR ("((structural functionalized) or (structural functionalization))")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"structural functionalism\") OR (\"structural functional\"))) or (\"structure functions\"))) or (\"((structural functionalized) or (structural functionalization))\"))".
• Removing quotes may allow a broader search: (((((( structural functionalism ) OR ( structural functional ))) or ( structure functions ))) or ( ((structural functionalized) or (structural functionalization)) )).
• Adding a wildcard symbol may retrieve word variants: (((((("structural functionalism") OR ("structural functional"))) or ("structure functions"))) or ("((structural functionalized) or (structural functionalization))"))*.
