• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chieu)) xanh - ((hanh manh) OR (hoang manh)) cua thong cong dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chieu)) xanh - ((hanh manh) OR (hoang manh)) cua thong cong dan toan ban*".
