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