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