• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh tran van thuong luong ((((dao than) OR (dao thanh))) OR (dao thai)) cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh tran van thuong luong ((((dao than) OR (dao thanh))) or (dao thai)) cap~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh tran van thuong luong ((((dao than) OR (dao thanh))) or (dao thai)) cap*.
