• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho trieu) OR (mot trieu)) tinh - thanh trung ((tuan tong) OR (toan thong)) cong van thanh cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (mot trieu)) tinh - thanh trung ((tuan tong) or (toan thong)) cong van thanh cao".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (mot trieu)) tinh - thanh trung ((tuan tong) or (toan thong)) cong van thanh cao*.
