• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tu) OR (sach thu)) tong xa hoi. hieu hieu cac xuc ((va thanh) OR (ban hanh)) vai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tu) OR (sach thu)) tong xa hoi. hieu hieu cac xuc ((va thanh) or (ban hanh)) vai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tu) OR (sach thu)) tong xa hoi. hieu hieu cac xuc ((va thanh) or (ban hanh)) vai cuu tre*.
