• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky lang xa hoi. hieu van ((cham xuc) OR (cam xuc)) va thanh san ((hau treo) OR (cau theo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky lang xa hoi. hieu van ((cham xuc) or (cam xuc)) va thanh san ((hau treo) OR (cau theo))".
