Perhaps you should try some spelling variations:
"sulla materiale" » "cultura materiale", "sulfur materials"
alma materiali » li materiali, fma material, sma materials
"alma materiale" » "als materiale", "na materiale", "alma mater.de"
pmma material » fma material, mia material, plasma material

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