• The words AND, OR and NOT may confuse the search; try adding quotes: "(( phung thi quen vang. nguoi duong hoc mot ) OR ( nhung ba quan luan. nguoi nung hoc mon ))~".
• Adding a wildcard symbol may retrieve word variants: (( phung thi quen vang. nguoi duong hoc mot ) OR ( nhung ba quan luan. nguoi nung hoc mon ))*.
