• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu sach)) - thanh trung ((cua khong) OR (cua phuong)) cong ban thanh cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu sach)) - thanh trung ((cua khong) or (cua phuong)) cong ban thanh cau".
