Perhaps you should try some spelling variations:
e literature » e literatur, life literature, prose literature
filosofia e » filosofia de, filosofia del
studio der » studio oder, studio del, studio de
studio dei » studio di, studio del, estudio del
tesi » test, teso, temi

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "tesi allo ((studio der) OR (studio dei)) filosofia e literature*".
