Perhaps you should try some spelling variations:
modell studien » moderne studien, modern studies, model student
models studies » modern studies, modeling studies, models study
del literatura » de literatura, pela literatura, da literatura
model studies » model study
e filosofia » la filosofia

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: rosi ((((modell studien) OR (models studies))) OR (model studies)) e filosofia del literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "rosi ((((modell studien) OR (models studies))) or (model studies)) e filosofia del literatura".
• Adding a wildcard symbol may retrieve word variants: rosi ((((modell studien) OR (models studies))) or (model studies)) e filosofia del literatura*.
