• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh trung cua nhung ((cong dan) OR (huong dan)) ((than cap) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh trung cua nhung ((cong dan) or (huong dan)) ((than cap) OR (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh trung cua nhung ((cong dan) or (huong dan)) ((than cap) OR (thanh lap))*.
