• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) sang - anh hung cua ((nhung cong) OR (hang cong)) tac trai cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) sang - anh hung cua ((nhung cong) or (hang cong)) tac trai cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) sang - anh hung cua ((nhung cong) or (hang cong)) tac trai cau*.
