• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach tu ((nang xa) OR (nang ma)) hoi. hieu ban thanh xuc va hanh vai ((cau tren) OR (la tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach tu ((nang xa) OR (nang ma)) hoi. hieu ban thanh xuc va hanh vai ((cau tren) or (la tren))*".
