• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang ((x hoi) OR (o hoi)). hieu ve cam tuc va ((thanh hoai) or (thanh hai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang ((x hoi) OR (o hoi)). hieu ve cam tuc va ((thanh hoai) OR (thanh hai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang ((x hoi) OR (o hoi)). hieu ve cam tuc va ((thanh hoai) or (thanh hai)) cua triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang ((x hoi) OR (o hoi)). hieu ve cam tuc va ((thanh hoai) or (thanh hai)) cua triet*.
