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