Perhaps you should try some spelling variations:
del litterature » de litterature, des litteratures, et litterature
mexico durante » mexico during, mexico ante
texto durante » bello durante, quito durante
die filosofia » di filosofia, de filosofia, e filosofia
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: "((texto durante) OR (mexico durante)) studien die filosofia del litterature".
• Adding a wildcard symbol may retrieve word variants: ((texto durante) OR (mexico durante)) studien die filosofia del litterature*.
