• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ha me ((gioi lam) OR (nguoi lam)) tdong tin ) OR ( tu sach bai me giai con hong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ha me ((gioi lam) OR (nguoi lam)) tdong tin ) or ( tu sach bai me giai con hong tin ))*".
