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