• Performing a fuzzy search may retrieve terms with similar spellings: so sach thu tang van hoi. hieu va cam xuc va thanh vi ((((cua tu) OR (cua cu))) or (cua su))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach thu tang van hoi. hieu va cam xuc va thanh vi ((((cua tu) OR (cua cu))) OR (cua su)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach thu tang van hoi. hieu va cam xuc va thanh vi ((((cua tu) OR (cua cu))) or (cua su))".
• Adding a wildcard symbol may retrieve word variants: so sach thu tang van hoi. hieu va cam xuc va thanh vi ((((cua tu) OR (cua cu))) or (cua su))*.
