Perhaps you should try some spelling variations:
large studien » lage studien, large student, large strain
de filologia » di filologia, e fisiologia
de filosofia » e filosofia, di filosofia, la filosofia
y literatura » la literatura
tests large » test large, tests target, jets large

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: "tests large studien ((de filologia) OR (de filosofia)) y literatura".
• Adding a wildcard symbol may retrieve word variants: tests large studien ((de filologia) OR (de filosofia)) y literatura*.
