• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((su sach) OR (so sach)) e de giai con thong minh ) OR ( toc sach san ma nguoi co hoang minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((su sach) OR (so sach)) e de giai con thong minh ) or ( toc sach san ma nguoi co hoang minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((su sach) OR (so sach)) e de giai con thong minh ) or ( toc sach san ma nguoi co hoang minh ))*.
