• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh ((chuong cua) OR (huong cua)) nhung cong ((ban hanh) OR (van thanh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((chuong cua) OR (huong cua)) nhung cong ((ban hanh) or (van thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((chuong cua) OR (huong cua)) nhung cong ((ban hanh) or (van thanh)) cau*.
