• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ((y nang) or (ly nang)) ma hoi. hieu van cau xuc va hanh doi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ((y nang) or (ly nang)) ma hoi. hieu van cau xuc va hanh doi cua triet*.
