• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (nhieu tang)) - hanh trung tranh nhung cong ((san toan) OR (dan toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (nhieu tang)) - hanh trung tranh nhung cong ((san toan) OR (dan toan)) tap*.
