• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach cha ve gioi cong dong minh ) or ( te sach ha me ((nguoi co) OR (nguoi do)) hoang minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach cha ve gioi cong dong minh ) OR ( te sach ha me ((nguoi co) OR (nguoi do)) hoang minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach cha ve gioi cong dong minh ) or ( te sach ha me ((nguoi co) OR (nguoi do)) hoang minh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach cha ve gioi cong dong minh ) or ( te sach ha me ((nguoi co) OR (nguoi do)) hoang minh ))*.
