Perhaps you should try some spelling variations:
spaces studied » species studied, space studies, states studied
spaces studie » space studies, spaces stable, spaces state
d filosofia » di filosofia, de filosofia, da filosofia
filosofia e » filosofia de, filosofia del
literatur » literature

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: "list ((spaces studie) OR (spaces studied)) d filosofia e literatur".
• Adding a wildcard symbol may retrieve word variants: list ((spaces studie) OR (spaces studied)) d filosofia e literatur*.
