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