• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien anh) OR (thien thanh)) - hanh trinh quan thuong cong ((khanh van) or (thanh van)) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien anh) OR (thien thanh)) - hanh trinh quan thuong cong ((khanh van) or (thanh van)) ban*.
