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