Perhaps you should try some spelling variations:
e litterature » et litterature, de litterature, en litterature
studies dne » studies dna, studies die, studies doe
filologia e » filologica e, fisiologia e, filologici e
studies dn » studies ds, studies d
rate game » state game, frame game, game game

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: rate game ((studies dne) OR (studies dn)) filologia e litterature.
• Adding a wildcard symbol may retrieve word variants: rate game ((studies dne) or (studies dn)) filologia e litterature*.
