• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang hoa hoi. hieu va cam ly anh ((luan vi) OR (luan ve)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) nang hoa hoi. hieu va cam ly anh ((luan vi) or (luan ve)) cua tre".
