Perhaps you should try some spelling variations:
del literatura » de literatura, pela literatura, da literatura
scale studien » scale studies, scale student, duale studien
scale studie » scale studies, scale study, sociale studies
2 filosofia » e filosofia, a filosofia, y 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: "just ((scale studie) OR (scale studien)) 2 filosofia del literatura*".
