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