• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach che ly nguoi cong thuong tin ) OR ( tu sach ((bao me) OR (bo me)) gioi con thong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach che ly nguoi cong thuong tin ) or ( tu sach ((bao me) OR (bo me)) gioi con thong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach che ly nguoi cong thuong tin ) or ( tu sach ((bao me) OR (bo me)) gioi con thong tin ))*.
