• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu manh) OR (chieu xanh)) - hanh trang quang dung hong van ((quan cu) OR (quan cua))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (chieu xanh)) - hanh trang quang dung hong van ((quan cu) OR (quan cua))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (chieu xanh)) - hanh trang quang dung hong van ((quan cu) OR (quan cua))*.
