Perhaps you should try some spelling variations:
approches interdisciplinares » approches interdisciplinaires, approaches interdisciplinary, approccio interdisciplinare
interdisciplinares e » interdisciplinares em, interdisciplinaires et, interdisciplinari e
la lecture » a lecture, a lecturer, m.a lecturer
lettre » lettres

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: "approches interdisciplinares e ((la lecture) OR (la lettre))".
• Adding a wildcard symbol may retrieve word variants: approches interdisciplinares e ((la lecture) OR (la lettre))*.
