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