• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien hach) or (hieu cach)) - hanh trang cua nhung cong van ((thanh tap) OR (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien hach) or (hieu cach)) - hanh trang cua nhung cong van ((thanh tap) OR (thanh lap))*.
