• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach tu nang ma hoi. hieu van cau ((xuc van) OR (luc van)) hanh hai ((chau treo) OR (cau theo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tu nang ma hoi. hieu van cau ((xuc van) or (luc van)) hanh hai ((chau treo) OR (cau theo))*".
