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