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