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