• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) xanh - canh ((tranh luan) OR (trinh quan)) tong cong ban thanh cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) xanh - canh ((tranh luan) or (trinh quan)) tong cong ban thanh cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (hoc hien)) xanh - canh ((tranh luan) or (trinh quan)) tong cong ban thanh cau*.
