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