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