• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((hang cua) OR (huong cua)) hoi. hieu va cac duc va ((danh vi) OR (dinh vi)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((hang cua) OR (huong cua)) hoi. hieu va cac duc va ((danh vi) or (dinh vi)) su triet".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((hang cua) OR (huong cua)) hoi. hieu va cac duc va ((danh vi) or (dinh vi)) su triet*.
