Perhaps you should try some spelling variations:
einer studenten » einer studentin, eine studentin, der studenten
eines studenten » die studenten, des studenten, eines dokumenten
filosofico de » filosoficos de, filosofico e, filosofico di
de literatura » de litterature, la literatura, y literatura
y filosofico » y filosoficos, y filosofia, e filosofica

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: "nebst ((einer studenten) OR (eines studenten)) y filosofico de literatura*".
