• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cac) OR (te cao)) ky tang hoa hoi. hieu ((qua cham) OR (qua than)) soc ban thanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) OR (te cao)) ky tang hoa hoi. hieu ((qua cham) or (qua than)) soc ban thanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te cac) OR (te cao)) ky tang hoa hoi. hieu ((qua cham) or (qua than)) soc ban thanh di cua tre*.
