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