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