• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ta trang xa hoi. hieu ve cham tuc va ((danh vai) OR (doanh van)) ((cuu tre) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ta trang xa hoi. hieu ve cham tuc va ((danh vai) or (doanh van)) ((cuu tre) OR (cua tre))*".
