Perhaps you should try some spelling variations:
e literature » e literatur, life literature, prose literature
filosofia e » filosofia de, filosofia del
studium a » studium am, studium ad, studium _
studium 1 » studium _, studium 3, studium 8
testo » test, tests, texto

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: testo duale ((((studium a) OR (studium 1))) OR (((studium a) OR (studium 1))m)) filosofia e literature*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "testo duale ((((studium a) OR (studium 1))) or (((studium a) OR (studium 1))m)) filosofia e literature*".
