• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) v nang xa hoi. thien van hau ((luoc van) OR (duc van)) hanh dieu cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) v nang xa hoi. thien van hau ((luoc van) or (duc van)) hanh dieu cua tre".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) v nang xa hoi. thien van hau ((luoc van) or (duc van)) hanh dieu cua tre*.
