• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky tang ha noi. ((hieu tu) OR (hien tu)) cham xuc van hanh vi ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ky tang ha noi. ((hieu tu) or (hien tu)) cham xuc van hanh vi ((cua tre) OR (cuu tre))".
