• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - canh tranh va ((thuong cong) OR (thong cong)) ((van tan) OR (van tuan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - canh tranh va ((thuong cong) OR (thong cong)) ((van tan) or (van tuan)) ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh tranh va ((thuong cong) OR (thong cong)) ((van tan) or (van tuan)) ban*.
