• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - thanh trung van dung cong dan ((toan cao) OR (van ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - thanh trung van dung cong dan ((toan cao) or (van ban))".
