Perhaps you should try some spelling variations:
del literatura » pela literatura, da literatura, e literatura
scale studien » scale studies, scale student, duale studien
de literatura » de litterature, la literatura, y literatura
texto scale » femto scale, texture scale, texto social
4 filosofia » e filosofia, a filosofia, y filosofia
studien 4 » studien _, studien 3, studien 5

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 scale studien 4 filosofia ((del literatura) OR (de literatura))".
• Adding a wildcard symbol may retrieve word variants: texto scale studien 4 filosofia ((del literatura) OR (de literatura))*.
