• Performing a fuzzy search may retrieve terms with similar spellings: (("hoi vat chat.") OR ((("hoi van chat.") OR ((("hoi van chan.") OR ("hoi van chon."))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"hoi vat chat.\") OR (((\"hoi van chat.\") OR (((\"hoi van chan.\") OR (\"hoi van chon.\"))))))".
• Removing quotes may allow a broader search: (( hoi vat chat. ) OR ((( hoi van chat. ) OR ((( hoi van chan. ) OR ( hoi van chon. )))))).
• Adding a wildcard symbol may retrieve word variants: (("hoi vat chat.") OR ((("hoi van chat.") OR ((("hoi van chan.") OR ("hoi van chon."))))))*.
