• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly nang ma hoa. thi ((van cam) OR (van nam)) tuc va ((danh hau) OR (manh hai)) cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly nang ma hoa. thi ((van cam) OR (van nam)) tuc va ((danh hau) or (manh hai)) cau tren".
• Adding a wildcard symbol may retrieve word variants: su sach ly nang ma hoa. thi ((van cam) OR (van nam)) tuc va ((danh hau) or (manh hai)) cau tren*.
