• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ly nang) OR (ky nang)) xa hoi. hieu ve cham luc tai doanh van ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ly nang) OR (ky nang)) xa hoi. hieu ve cham luc tai doanh van ((cua tre) or (cua te))*".
