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

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: (((("economies politique") OR ("economico politique"))) OR ("oeconomique politique"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"economies politique\") OR (\"economico politique\"))) or (\"oeconomique politique\"))*".
• Removing quotes may allow a broader search: (((( economies politique ) OR ( economico politique ))) or ( oeconomique politique ))*.
