• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) or (hieu lang)) - canh doanh luan hang thong ((minh van) OR (vinh van)) ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sang) or (hieu lang)) - canh doanh luan hang thong ((minh van) OR (vinh van)) ban*.
