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