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