• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach cha me giai cao phong minh ) OR ( te sach ((nha ve) OR (nhat ve)) giao mo phong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach cha me giai cao phong minh ) or ( te sach ((nha ve) OR (nhat ve)) giao mo phong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( te sach cha me giai cao phong minh ) or ( te sach ((nha ve) OR (nhat ve)) giao mo phong minh ))*.
