• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (ky nang)) ma hoi. hieu ((va cham) OR (va chat)) luc va hanh cat cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) OR (ky nang)) ma hoi. hieu ((va cham) or (va chat)) luc va hanh cat cua triet".
