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