• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sang)) - ((nhanh luong) OR (nhanh quang)) cua nhung cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - ((nhanh luong) or (nhanh quang)) cua nhung cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - ((nhanh luong) or (nhanh quang)) cua nhung cong dan than cau*.
