• Performing a fuzzy search may retrieve terms with similar spellings: (("di san thien hien.") OR ((("di can thiet nhien.") OR ("di va thiet nhien."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"di san thien hien.\") OR (((\"di can thiet nhien.\") OR (\"di va thiet nhien.\"))))".
• Removing quotes may allow a broader search: (( di san thien hien. ) OR ((( di can thiet nhien. ) OR ( di va thiet nhien. )))).
• Adding a wildcard symbol may retrieve word variants: (("di san thien hien.") OR ((("di can thiet nhien.") OR ("di va thiet nhien."))))*.
