• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang xa) OR (nang ma)) hoi. thi nang ((cham duc) OR (cham soc)) va danh vinh cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang xa) OR (nang ma)) hoi. thi nang ((cham duc) or (cham soc)) va danh vinh cau tren".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang xa) OR (nang ma)) hoi. thi nang ((cham duc) or (cham soc)) va danh vinh cau tren*.
