• If you are trying to use Boolean operators, they must be ALL CAPS: (( toc sach pha ve gioi co phong minh ) OR ( tu sach ((ha de) OR (hat de)) giai cac thong minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( toc sach pha ve gioi co phong minh ) or ( tu sach ((ha de) OR (hat de)) giai cac thong minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( toc sach pha ve gioi co phong minh ) or ( tu sach ((ha de) OR (hat de)) giai cac thong minh ))*.
