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