• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang van hoe. lieu va nay luc ((va danh) OR (va hanh)) ((va dau) OR (va dao)) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang van hoe. lieu va nay luc ((va danh) or (va hanh)) ((va dau) OR (va dao)) tren".
