• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky dang) OR (ky danh)) ((cay phoi) OR (cay cho)). hieu van lam luc va hanh va cau trieu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky dang) or (ky danh)) ((cay phoi) OR (cay cho)). hieu van lam luc va hanh va cau trieu*".
