• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang xa) or (((nang ma) OR (tang ma)))) hoi. hieu va cac xuc va doanh cua cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((lang xa) or (((nang ma) OR (tang ma)))) hoi. hieu va cac xuc va doanh cua cua triet*.
