• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (do sanh)) ky lang xa hoi. hieu hien ((bach nuoc) OR (bich ngoc)) va danh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (do sanh)) ky lang xa hoi. hieu hien ((bach nuoc) OR (bich ngoc)) va danh vi cua tu*".
