• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tay) OR (sach nay)) lang xa hoi. hieu ve cam xuc va ((danh thai) OR (anh thai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tay) or (sach nay)) lang xa hoi. hieu ve cam xuc va ((danh thai) OR (anh thai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tay) or (sach nay)) lang xa hoi. hieu ve cam xuc va ((danh thai) OR (anh thai)) cua tre*.
