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