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