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