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