• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc thieu)) xanh - manh trung thanh trong ((cong dan) OR (cong san)) than cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc thieu)) xanh - manh trung thanh trong ((cong dan) OR (cong san)) than cao*".
