• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac ky ((nang mai) or (((nang tai) OR (sang tai)))) hoi. hieu ve cac dac va anh thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: su cac ky ((nang mai) or (((nang tai) OR (sang tai)))) hoi. hieu ve cac dac va anh thai cua tre*.
