Perhaps you should try some spelling variations:
die filosofica » di filosofia, e filosofica, vida filosofica
space studien » space studies, spaces studied, space student
de filosofia » e filosofia, di filosofia, la filosofia
lists space » its space, bits space, list spaces

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: "lists space studien ((die filosofica) OR (de filosofia)) _ literatura".
• Adding a wildcard symbol may retrieve word variants: lists space studien ((die filosofica) OR (de filosofia)) _ literatura*.
