• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((v sang) OR (_ sang)) tai hoi. hieu ve cham soc ((va danh) OR (va dinh)) dien cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((v sang) OR (_ sang)) tai hoi. hieu ve cham soc ((va danh) or (va dinh)) dien cua tre".
