Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da
d filosofia » di filosofia, de filosofia, da filosofia
test scale » tests scale, rest scale, treat scale
best scale » bast scale, rest scale, burst scale

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: "((test scale) OR (best scale)) study d filosofia la literatura*".
