• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ky) OR (sach ty)) nang xa hoi. hieu ve cam tuc ((xa huong) OR (xa phuong)) dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach ky) OR (sach ty)) nang xa hoi. hieu ve cam tuc ((xa huong) or (xa phuong)) dai cua tre".
• Adding a wildcard symbol may retrieve word variants: so ((sach ky) OR (sach ty)) nang xa hoi. hieu ve cam tuc ((xa huong) or (xa phuong)) dai cua tre*.
