• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) OR (chieu sang)) - thanh tung ((dap nhung) or (vap nhung)) dong ban than cap~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) OR (chieu sang)) - thanh tung ((dap nhung) or (vap nhung)) dong ban than cap*.
