• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu nganh) OR (hieu manh)) - hanh trang cua nhung song van ((thuan cam) OR (quan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu nganh) OR (hieu manh)) - hanh trang cua nhung song van ((thuan cam) or (quan cau))~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu nganh) OR (hieu manh)) - hanh trang cua nhung song van ((thuan cam) or (quan cau))*.
