• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tu nong co loi. hieu ve cham ((xac va) OR (((tuc va) OR (thuc va)))) thanh lai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tu nong co loi. hieu ve cham ((xac va) or (((tuc va) OR (thuc va)))) thanh lai cua tre*".
