Perhaps you should try some spelling variations:
e literatura » de literatura, y literatura, e literatur
filosofia e » filosofia de, filosofia del
tesi delle » testi delle, testi della, beni delle
test delle » testi delle, test della, testa della
studien la » studien lap, studien a, studien l

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 delle) OR (test delle)) studien la filosofia e literatura".
• Adding a wildcard symbol may retrieve word variants: ((tesi delle) OR (test delle)) studien la filosofia e literatura*.
