• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach y)) ((nang xa) OR (lang ha)) hoi. lieu va phat thuc va thanh vien cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach y)) ((nang xa) or (lang ha)) hoi. lieu va phat thuc va thanh vien cua tre".
