Perhaps you should try some spelling variations:
die filosofica » di filosofia, de filosofia, e filosofica
space studien » space studies, spaces studied, space student
a literatura » la literatura, y literatura, a literatur
lists space » its space, bits space, list spaces
studien die » studie die, studien der

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