• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"mediacion de campo a valero la ;\\") or (\\"medicion de campo y ((loa pau) OR (la pau)) ;\\"))*\"".
• Removing quotes may allow a broader search: (( mediacion de campo a valero la ; ) or ( medicion de campo y ((loa pau) OR (la pau)) ; ))*.
