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