• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((hieu lang) OR (hieu quang)) - thanh truong cua trong cong tac ((thanh mau) or (thanh hai))~".
• Adding a wildcard symbol may retrieve word variants: doi ((hieu lang) OR (hieu quang)) - thanh truong cua trong cong tac ((thanh mau) or (thanh hai))*.
