• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi xanh - thanh ((truong cua) OR (truong cao)) dung ((cong ban) OR (cong bang)) thanh cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi xanh - thanh ((truong cua) or (truong cao)) dung ((cong ban) OR (cong bang)) thanh cap~".
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - thanh ((truong cua) or (truong cao)) dung ((cong ban) OR (cong bang)) thanh cap*.
