• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang xa) OR (lang van)) hoi. hieu qua ((cac xuc) OR (cam xuc)) ban linh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang xa) or (lang van)) hoi. hieu qua ((cac xuc) OR (cam xuc)) ban linh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((nang xa) or (lang van)) hoi. hieu qua ((cac xuc) OR (cam xuc)) ban linh hai cua tre*.
