Perhaps you should try some spelling variations:
models studies » model studies, modeling studies, models study
modern studies » model studies, modeling studies, modelling studies
filosofia le » filosofia de, filosofia del, filosofia da
filosofia e » filosofia de, filosofia del

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