• If you are trying to use Boolean operators, they must be ALL CAPS: te sach va ((nang xa) OR (nang ma)) hoi. hieu ve cham soc ((va dan) OR (va dao)) dien cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach va ((nang xa) or (nang ma)) hoi. hieu ve cham soc ((va dan) OR (va dao)) dien cua tu".
