• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc lieu) OR (du lieu)) tinh - thanh tran thanh han tong ban ((hang san) OR (hanh san))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc lieu) OR (du lieu)) tinh - thanh tran thanh han tong ban ((hang san) or (hanh san))*".
