• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky nang xa hoi. hieu ((va cam) OR (va cao)) xuc xa phuong doi ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang xa hoi. hieu ((va cam) OR (va cao)) xuc xa phuong doi ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang xa hoi. hieu ((va cam) OR (va cao)) xuc xa phuong doi ((cua te) or (cua tu))".
