Perhaps you should try some spelling variations:
des filologia » de filologia, di filologia, de fisiologia
e literatura » de literatura, y literatura, e literatur
e filologia » de filologia, di filologia, e fisiologia
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: "text das studium ((des filologia) OR (e filologia)) e literatura".
• Adding a wildcard symbol may retrieve word variants: text das studium ((des filologia) OR (e filologia)) e literatura*.
