• If you are trying to use Boolean operators, they must be ALL CAPS: ve cac ky tang ha noi. hieu qua tham soc ban thanh ((((di cua) OR (de cua))) OR (dai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ve cac ky tang ha noi. hieu qua tham soc ban thanh ((((di cua) OR (de cua))) or (dai cua)) tre*".
