• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (hieu lang)) - thanh ((trung tuan) OR (trung thanh)) dong cong van thanh cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (hieu lang)) - thanh ((trung tuan) OR (trung thanh)) dong cong van thanh cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (hieu lang)) - thanh ((trung tuan) OR (trung thanh)) dong cong van thanh cau*.
