Perhaps you should try some spelling variations:
del literatura » de literatura, pela literatura, da literatura
scale studien » scale studies, duale studien, soziale studien
scale student » late student, scale study, scale studies
die filosofia » di filosofia, de filosofia, e filosofia

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: "sets ((scale studien) OR (scale student)) die filosofia del literatura*".
