• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y lang) OR (_ lang)) xa hoi. ((hieu vu) OR (hieu va)) cham vuc van minh lai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y lang) OR (_ lang)) xa hoi. ((hieu vu) or (hieu va)) cham vuc van minh lai cua tre*".
