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