Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, duale studien
es filosofia » em filosofia, la filosofia, di filosofia
y literatura » la literatura
burst scale » bast scale, best scale, just scale
e filosofia » la 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: "burst scale studien ((es filosofia) OR (e filosofia)) y literatura".
• Adding a wildcard symbol may retrieve word variants: burst scale studien ((es filosofia) OR (e filosofia)) y literatura*.
