• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) ((nang xa) OR (lang van)) hoi. hieu van cam duc van thang loi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) ((nang xa) or (lang van)) hoi. hieu van cam duc van thang loi cua tre".
