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