• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky tang ha hoi. hieu qua tham soc ban ((thanh di) OR (thanh do)) ((cua tre) OR (cua vat))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky tang ha hoi. hieu qua tham soc ban ((thanh di) OR (thanh do)) ((cua tre) or (cua vat))*".
