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