chieu sang » chieu sach, chieu xanh, hieu lang
cua phuong » cuu phuong, cuc phuong, luan phuong
hanh tinh » hanh trinh, nhanh tinh, thanh tinh

• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chiet tach) OR (chieu sang)) - hanh tinh cua phuong cong ((van ban) OR (van tuan)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho ((chiet tach) or (chieu sang)) - hanh tinh cua phuong cong ((van ban) or (van tuan)) cau*.
