• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu san) OR (tu can)) ky ((nang xa) OR (tang ma)) hoi. hieu va chat thuc day don vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) OR (tu can)) ky ((nang xa) or (tang ma)) hoi. hieu va chat thuc day don vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu san) OR (tu can)) ky ((nang xa) or (tang ma)) hoi. hieu va chat thuc day don vai cua tre*.
