• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sac ky nang xa hoi. hieu ve ((cau thuc) OR (cau truc)) van hoang vi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sac ky nang xa hoi. hieu ve ((cau thuc) or (cau truc)) van hoang vi ((cua tre) OR (cua triet))".
