• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien nhanh)) - ((thanh tran) OR (thanh tra)) tuan cong cong van toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien nhanh)) - ((thanh tran) or (thanh tra)) tuan cong cong van toan ban*".
