Perhaps you should try some spelling variations:
"etudes de droit international" » "etudes de first international", "etudes de 21st international", "etudes du droit international", "etudes le droit international"
"etudes de joint international" » "etudes de 21st international", "etudes die joint international", "etudes he joint international", "etudes one joint international"
"etudes en 1st international" » "etudes en 21st international", "etudes en first international", "etude et 1st international", "etudes _ 1st international", "etudes a 1st international"

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: (((("etudes de droit international") OR ("etudes de joint international"))) OR ("etudes en 1st international")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"etudes de droit international\") OR (\"etudes de joint international\"))) or (\"etudes en 1st international\"))".
• Removing quotes may allow a broader search: (((( etudes de droit international ) OR ( etudes de joint international ))) or ( etudes en 1st international )).
• Adding a wildcard symbol may retrieve word variants: (((("etudes de droit international") OR ("etudes de joint international"))) or ("etudes en 1st international"))*.
