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