• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky lang xa hoi. ((hieu viec) OR (((sieu viet) OR (dien viet)))) cac loc va danh dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky lang xa hoi. ((hieu viec) or (((sieu viet) OR (dien viet)))) cac loc va danh dai cua te*".
