• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sang) OR (chieu tinh)) - thanh truong cao nhung ((cong tan) OR (cong san)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) or (chieu tinh)) - thanh truong cao nhung ((cong tan) OR (cong san)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sang) or (chieu tinh)) - thanh truong cao nhung ((cong tan) OR (cong san)) toan ban*.
