• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (te sach)) ky tang xa hoi. hieu ve cau phuc va dinh dao ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (te sach)) ky tang xa hoi. hieu ve cau phuc va dinh dao ((cuu tre) OR (cau treo))".
