• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - ((((hanh tang) OR (anh tang))) OR (thanh trung)) cua thuong trong ban than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - ((((hanh tang) OR (anh tang))) or (thanh trung)) cua thuong trong ban than cau~".
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - ((((hanh tang) OR (anh tang))) or (thanh trung)) cua thuong trong ban than cau*.
