• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (diep tinh)) - hanh trung cap nhung hong ((van toan) OR (van thanh)) ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (diep tinh)) - hanh trung cap nhung hong ((van toan) OR (van thanh)) ban*.
