• If you are trying to use Boolean operators, they must be ALL CAPS: tu cai ky nang van hoi. hieu ve cham ((xuc ban) OR (cuc ban)) thanh hai ((cau treo) OR (cau triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cai ky nang van hoi. hieu ve cham ((xuc ban) OR (cuc ban)) thanh hai ((cau treo) or (cau triet))".
