• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - thanh truong ((((va trong) OR (va trung))) OR (va thong)) cong ban hang tai~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu xanh - thanh truong ((((va trong) OR (va trung))) or (va thong)) cong ban hang tai~".
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - thanh truong ((((va trong) OR (va trung))) or (va thong)) cong ban hang tai*.
