• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tran van giang.\") OR (((\"luan tran giang.\") OR (\"luan trong giang.\"))))~".
• Removing quotes may allow a broader search: (( tran van giang. ) OR ((( luan tran giang. ) OR ( luan trong giang. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("tran van giang.") OR ((("luan tran giang.") OR ("luan trong giang."))))*.
