Perhaps you should try some spelling variations:
die filosofica » di filosofia, de filosofia, vida filosofica
la literatura » la litterature, a literature
duale studie » duale studien, duale studium, duales studium
e filosofica » e filosofia, e filosofiche, a filosofia
best duale » best deal, best deals, best 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: "best duale studie ((die filosofica) OR (e filosofica)) la literatura*".
