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