• Performing a fuzzy search may retrieve terms with similar spellings: su cac tu nano 1 ho. ((hieu ve) OR (hieu van)) cham duc va hanh vi ((cua triet) or (cua vat))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac tu nano 1 ho. ((hieu ve) OR (hieu van)) cham duc va hanh vi ((cua triet) OR (cua vat)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac tu nano 1 ho. ((hieu ve) OR (hieu van)) cham duc va hanh vi ((cua triet) or (cua vat))".
• Adding a wildcard symbol may retrieve word variants: su cac tu nano 1 ho. ((hieu ve) OR (hieu van)) cham duc va hanh vi ((cua triet) or (cua vat))*.
