• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach ha va nguoi ((duc hoang) OR (duc hung)) minh ) OR ( so sach ha va giai toa thong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach ha va nguoi ((duc hoang) OR (duc hung)) minh ) or ( so sach ha va giai toa thong minh ))".
