• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - ((anh tang) OR (nhanh lang)) cua thong ((cong van) OR (cong vang)) tuan phan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - ((anh tang) or (nhanh lang)) cua thong ((cong van) OR (cong vang)) tuan phan~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((anh tang) or (nhanh lang)) cua thong ((cong van) OR (cong vang)) tuan phan*.
