• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo chu)) sach - ((hanh mang) OR (nhanh mang)) vua dung huong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (theo chu)) sach - ((hanh mang) OR (nhanh mang)) vua dung huong dan than cau".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo chu)) sach - ((hanh mang) OR (nhanh mang)) vua dung huong dan than cau*.
