• If you are trying to use Boolean operators, they must be ALL CAPS: so sang ky nang xa hoi. ((hieu va) OR (hieu qua)) co suc gia ((thanh ca) OR (thanh cac)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sang ky nang xa hoi. ((hieu va) or (hieu qua)) co suc gia ((thanh ca) OR (thanh cac)) cua te".
