• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sang) OR (hieu lang)) - hanh trinh qua cong cong ((nhan chuan) OR (nhan chan)) ha~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) or (hieu lang)) - hanh trinh qua cong cong ((nhan chuan) OR (nhan chan)) ha~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sang) or (hieu lang)) - hanh trinh qua cong cong ((nhan chuan) OR (nhan chan)) ha*.
