• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. ((hieu ve) OR (hieu va)) cam luc gia thanh vi ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. ((hieu ve) or (hieu va)) cam luc gia thanh vi ((cuu tre) OR (cau treo))".
