• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach (nha OR nhan) xe doi song thuong tinh ) OR ( thuat sach cha ke nguoi con hong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach (nha OR nhan) xe doi song thuong tinh ) or ( thuat sach cha ke nguoi con hong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach (nha OR nhan) xe doi song thuong tinh ) or ( thuat sach cha ke nguoi con hong tin ))*.
