Perhaps you should try some spelling variations:
"oeconomique politique" » "economiques politiques", "economie politique", "d'economie politique", "oeconomiques politiques", "oeconomie politique", "oeconomico politique"
"economique politique" » "economiques politiques", "economie politique", "economico politique"

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: "((\"economique politique\") OR (\"oeconomique politique\"))*".
• Removing quotes may allow a broader search: (( economique politique ) OR ( oeconomique politique ))*.
