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