• If you are trying to use Boolean operators, they must be ALL CAPS: co sach ky nang x hoi. hieu van ((cham xuc) OR (cam xuc)) ((va thanh) OR (va tinh)) phan cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "co sach ky nang x hoi. hieu van ((cham xuc) or (cam xuc)) ((va thanh) OR (va tinh)) phan cau tren".
