• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat sach)) ky dang mau hoi. hieu van cam duc va ((hanh vai) OR (hanh va)) cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (thuat sach)) ky dang mau hoi. hieu van cam duc va ((hanh vai) or (hanh va)) cua tu*".
