• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((ban ky) OR (dan ky)) tang ha noi. ((hieu tu) OR (hien tu)) cham xuc van hanh ve cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((ban ky) OR (dan ky)) tang ha noi. ((hieu tu) or (hien tu)) cham xuc van hanh ve cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((ban ky) OR (dan ky)) tang ha noi. ((hieu tu) or (hien tu)) cham xuc van hanh ve cua tre*.
