• If you are trying to use Boolean operators, they must be ALL CAPS: so sac ky ((nang cap) OR (nang cham)) hoi. ((hieu ve) OR (hieu va)) cam luc va hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky ((nang cap) OR (nang cham)) hoi. ((hieu ve) or (hieu va)) cam luc va hanh vai cua tre*".
