Perhaps you should try some spelling variations:
"oeconomique politique" » "economiques politiques", "d'economie politique", "l'economie politique"
"economico politique" » "economico politiques", "economico politiche", "economico politica"
"economic politique" » "economico politiques", "d'economie politique", "l'economie politique"
"economie politique" » "economies politique", "economique politique", "economics politique"

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: (((("economie politique") OR ((("economic politique") OR ("economico politique"))))) OR ("oeconomique politique")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"economie politique\") or (((\"economic politique\") OR (\"economico politique\"))))) or (\"oeconomique politique\"))".
• Removing quotes may allow a broader search: (((( economie politique ) or ((( economic politique ) OR ( economico politique ))))) or ( oeconomique politique )).
• Adding a wildcard symbol may retrieve word variants: (((("economie politique") or ((("economic politique") OR ("economico politique"))))) or ("oeconomique politique"))*.
