• If you are trying to use Boolean operators, they must be ALL CAPS: (( thuoc lanh dao me giai (doan OR dan) phuong tin ) OR ( te sach cha ve trai doanh thuong minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thuoc lanh dao me giai (doan OR dan) phuong tin ) or ( te sach cha ve trai doanh thuong minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( thuoc lanh dao me giai (doan OR dan) phuong tin ) or ( te sach cha ve trai doanh thuong minh ))*.
