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