Perhaps you should try some spelling variations:
"structural functionalization" » "structure functionalization", "structural functionality", "structural regionalization", "structure functionization", "structure functionsization"
structural functionalism » structural functions, structure functionality, structured functional
structure functional » structure function, structure functions

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