Perhaps you should try some spelling variations:
"sulla materiale" » "cultura materiale", "sulfur materials"
"alma materiali" » "li materiali", "pmma material", "sma materials"
"fma material" » "fea material", "pmma material", "sma materials"

Try widening your search to All Fields.

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: (((("alma materiali") OR ("fma material"))) OR ("sulla materiale")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"alma materiali\") OR (\"fma material\"))) or (\"sulla materiale\"))".
• Removing quotes may allow a broader search: (((( alma materiali ) OR ( fma material ))) or ( sulla materiale )).
• Adding a wildcard symbol may retrieve word variants: (((("alma materiali") OR ("fma material"))) or ("sulla materiale"))*.
