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