• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu nganh - manh trung ((tam hang) OR (((tam thuong) OR (tai thuong)))) cong dan thanh chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu nganh - manh trung ((tam hang) or (((tam thuong) OR (tai thuong)))) cong dan thanh chau~".
• Adding a wildcard symbol may retrieve word variants: doc hieu nganh - manh trung ((tam hang) or (((tam thuong) OR (tai thuong)))) cong dan thanh chau*.
