• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - anh ((trong quang) OR (trong quan)) dung thuong danh thanh san~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - anh ((trong quang) OR (trong quan)) dung thuong danh thanh san~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - anh ((trong quang) OR (trong quan)) dung thuong danh thanh san*.
