• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (((hieu lang) OR (chieu sang)))) - thanh tuong nao nhung cong dan phan dau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chiet tach) or (((hieu lang) OR (chieu sang)))) - thanh tuong nao nhung cong dan phan dau*.
