• If you are trying to use Boolean operators, they must be ALL CAPS: ((doan thien) OR (toan thiet)) anh - thanh tung cua ((nhung cong) OR (hang cong)) dang toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doan thien) OR (toan thiet)) anh - thanh tung cua ((nhung cong) or (hang cong)) dang toan tap*".
