• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ha ke nguoi han hoang minh ) OR ( tu sach ha ((ke giai) OR (kem giai)) can hoang minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ha ke nguoi han hoang minh ) or ( tu sach ha ((ke giai) OR (kem giai)) can hoang minh ))".
