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