• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (sach thu)) nang x hoi. hieu hien cao suc ((manh hanh) OR (minh thanh)) va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) or (sach thu)) nang x hoi. hieu hien cao suc ((manh hanh) OR (minh thanh)) va cua tre".
