• If you are trying to use Boolean operators, they must be ALL CAPS: theo chinh sach - canh tranh cua dung ((phuong lan) OR (phuong doan)) ((han tai) OR (van tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chinh sach - canh tranh cua dung ((phuong lan) or (phuong doan)) ((han tai) OR (van tai))~".
• Adding a wildcard symbol may retrieve word variants: theo chinh sach - canh tranh cua dung ((phuong lan) or (phuong doan)) ((han tai) OR (van tai))*.
