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