• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang ((mai khoi) OR (cac khoi)). hieu va cham xuc ban ((hang vi) OR (hang di)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang ((mai khoi) or (cac khoi)). hieu va cham xuc ban ((hang vi) OR (hang di)) cua te".
