• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) ((lang xa) or (hoang van)) hoi. thien van lam duc van doanh ban cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) ((lang xa) or (hoang van)) hoi. thien van lam duc van doanh ban cua tre*.
