• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach ly) OR (sach y)) nang ((xa hoi) OR (mai hoi)). lieu va cham luc van thanh vi tu tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach ly) OR (sach y)) nang ((xa hoi) or (mai hoi)). lieu va cham luc van thanh vi tu tren".
