• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu cac)) ky ((sang xa) OR (tang ma)) hoi. hieu van cam xuc va hanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu cac)) ky ((sang xa) or (tang ma)) hoi. hieu van cam xuc va hanh hai cua tre".
