• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((nang hai) OR (hang hai)) hoi. lieu ((va cam) OR (va cao)) xuc ban hang dieu cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ((nang hai) or (hang hai)) hoi. lieu ((va cam) OR (va cao)) xuc ban hang dieu cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach y ((nang hai) or (hang hai)) hoi. lieu ((va cam) OR (va cao)) xuc ban hang dieu cua tre*.
