• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty sang tao hoi. hieu vu cham soc ((((va hanh) OR (va thanh))) OR (va danh)) lai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty sang tao hoi. hieu vu cham soc ((((va hanh) OR (va thanh))) or (va danh)) lai cua tre*".
