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