• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((((chieu xanh) OR (chieu sang))) OR (trieu tinh)) - nhanh bac ca thuong cong san can cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((((chieu xanh) OR (chieu sang))) or (trieu tinh)) - nhanh bac ca thuong cong san can cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((((chieu xanh) OR (chieu sang))) or (trieu tinh)) - nhanh bac ca thuong cong san can cau*.
