• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ((ma hoi) OR (xa hoi)). hieu vu cham tuc va dan dat ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((ma hoi) or (xa hoi)). hieu vu cham tuc va dan dat ((cuu tre) OR (cau treo))".
