• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu van cam luc ((va thanh) OR (va tinh)) va ((chua tre) OR (chua tri)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu van cam luc ((va thanh) OR (va tinh)) va ((chua tre) or (chua tri))".
