• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (ho chieu)) tinh - anh nang du ((nhung cong) OR (hang cong)) tan tran cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (ho chieu)) tinh - anh nang du ((nhung cong) or (hang cong)) tan tran cau*".
