• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((tu cach) OR (tu cac)) ca me gioi con song tin ) OR ( thuat sach xa me doi song thuong binh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((tu cach) OR (tu cac)) ca me gioi con song tin ) or ( thuat sach xa me doi song thuong binh ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((tu cach) OR (tu cac)) ca me gioi con song tin ) or ( thuat sach xa me doi song thuong binh ))*.
