• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu xanh) OR (chieu sang))) OR (chieu sach)) - thanh tung vien thong cong tam toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (chieu sang))) or (chieu sach)) - thanh tung vien thong cong tam toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (chieu sang))) or (chieu sach)) - thanh tung vien thong cong tam toan ban*.
