• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (nhieu tang)) - hanh trung ((tranh nhung) OR (tran hung)) cong san toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (nhieu tang)) - hanh trung ((tranh nhung) OR (tran hung)) cong san toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (nhieu tang)) - hanh trung ((tranh nhung) OR (tran hung)) cong san toan tap*.
