• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (tien anh)) - canh ((tranh van) OR (trinh van)) nhung cong dan than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (tien anh)) - canh ((tranh van) OR (trinh van)) nhung cong dan than cap*".
