• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tu) OR (sach thu)) sang ma hoi. hieu ve cam xuc va ((thanh hoa) OR (hanh kem)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tu) OR (sach thu)) sang ma hoi. hieu ve cam xuc va ((thanh hoa) or (hanh kem)) cua triet".
