Perhaps you should try some spelling variations:
die filologica » di filologia, de filologia
double studie » double stage, double side, double saddle
yeast double » test double, year double, test doubles
e literatura » de literatura, y literatura, e literatur
e filologia » de filologia, di filologia, e fisiologia

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: "yeast double studie ((die filologica) OR (e filologia)) e literatura".
• Adding a wildcard symbol may retrieve word variants: yeast double studie ((die filologica) OR (e filologia)) e literatura*.
