• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. ((hieu ve) OR (hieu va)) cam xuc va ((thanh vi) OR (thanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. ((hieu ve) or (hieu va)) cam xuc va ((thanh vi) OR (thanh va)) cua tre".
