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