• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((nha nguoc) OR (nhan nguoi)) chieu ((nghia cua) OR (nghe cua)) ets : nhung van so va đai.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((nha nguoc) OR (nhan nguoi)) chieu ((nghia cua) or (nghe cua)) ets : nhung van so va đai".
