Perhaps you should try some spelling variations:
life literature » polite literature, prose literature
filosofia life » filosofia le, filosofia de, filosofia e
studien der » studie der, studenten der
test delle » testi delle, tesi delle, test della
studien di » studien die, studien dd, studien bei

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: "test delle ((studien di) OR (studien der)) filosofia life literature*".
