• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ly hang xa hoi. hieu va cam tuc van ((doanh tu) OR (doanh thu)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu bach)) ly hang xa hoi. hieu va cam tuc van ((doanh tu) OR (doanh thu)) cua te*".
