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