• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach hinh suu - ton giao ) OR ( ((thu sach) OR (thuat sach)) kinh su - ton giao )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach hinh suu - ton giao ) or ( ((thu sach) OR (thuat sach)) kinh su - ton giao ))".
