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