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