• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach nhan mac nguoi don thong minh ) OR ( tu sach ((ha ky) OR (ha my)) nguoi co thong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach nhan mac nguoi don thong minh ) or ( tu sach ((ha ky) OR (ha my)) nguoi co thong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach nhan mac nguoi don thong minh ) or ( tu sach ((ha ky) OR (ha my)) nguoi co thong tin ))*.
