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