• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky dinh van hoi. hieu ((va cam) OR (va cao)) cuc ban ((anh hai) OR (lanh hai)) chau tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky dinh van hoi. hieu ((va cam) OR (va cao)) cuc ban ((anh hai) or (lanh hai)) chau tre*".
