• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang xay hoi. hieu qua ((cau phuc) OR (huu phuc)) van hanh vi ((cua te) OR (cua tuc))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang xay hoi. hieu qua ((cau phuc) OR (huu phuc)) van hanh vi ((cua te) or (cua tuc))*".
