• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach tai lang xa hoi. hieu ((ve phan) OR (va phan)) dai ban hanh vi ((su triet) OR (su viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach tai lang xa hoi. hieu ((ve phan) or (va phan)) dai ban hanh vi ((su triet) OR (su viet))*".
