• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - thanh ((trung cua) OR (truong cua)) nhung cong dan ((than cau) OR (phan dau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - thanh ((trung cua) OR (truong cua)) nhung cong dan ((than cau) or (phan dau))*".
