Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da
y filosofia » e filosofia, a filosofia, la filosofia
texten das » texten des, texten der, texten aus
studium y » studium _, studium 1, studium 3
text das » text des, text data, text der

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: "((texten das) OR (text das)) studium y filosofia la literatura*".
