• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (hieu lang)) - banh trong cac dang ((thuong dan) OR (thuong dam)) phan lap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (hieu lang)) - banh trong cac dang ((thuong dan) OR (thuong dam)) phan lap".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (hieu lang)) - banh trong cac dang ((thuong dan) OR (thuong dam)) phan lap*.
