Perhaps you should try some spelling variations:
game studies » case studies
filologica e » filologici e, filosofica e, philologica de
studies doe » studies does, studies dose, studies do
filologia e » fisiologia e, filologici e, filosofia e
rate game » state game, frame game, game game

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: "rate game studies doe ((filologia e) OR (filologica e)) litterature".
• Adding a wildcard symbol may retrieve word variants: rate game studies doe ((filologia e) OR (filologica e)) litterature*.
