Perhaps you should try some spelling variations:
spaces studied » species studied, space studies, states studied
filosofia la » filosofia da, filosofia le, filosofica da
filosofia e » filosofia de, filosofia del
lis spaces » list spaces, lcs spaces, lens spaces
studied di » studied d, studied ii, studied vi

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

• If you are trying to use Boolean operators, they must be ALL CAPS: lis spaces studied di ((filosofia la) OR (filosofia e)) literature*.
