Perhaps you should try some spelling variations:
structural functionalized » structural functionalization, structure functionality, natural functionalized
"structural functionalism" » "structural functions", "structure functionality", "structure functional", "structure functionism"
structural functionality » structure functionality, structural conditionality, structural rationality
"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 ("structure functions"))) OR ("((structural functionalized) or (((structural functionality) OR (structural functional))))")).
• Removing quotes may allow a broader search: (((( structural functionalism ) or ( structure functions ))) or ( ((structural functionalized) or (((structural functionality) OR (structural functional)))) )).
• Adding a wildcard symbol may retrieve word variants: (((("structural functionalism") or ("structure functions"))) or ("((structural functionalized) or (((structural functionality) OR (structural functional))))"))*.
