• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi anh) OR (chi hanh)) - thanh tung tuan bang cong ((thanh toan) OR (thanh hoa)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi anh) or (chi hanh)) - thanh tung tuan bang cong ((thanh toan) OR (thanh hoa)) tap~".
• Adding a wildcard symbol may retrieve word variants: doi ((chi anh) or (chi hanh)) - thanh tung tuan bang cong ((thanh toan) OR (thanh hoa)) tap*.
