• If you are trying to use Boolean operators, they must be ALL CAPS: te sach kho tang ((((ha hoi) OR (xa hoi))) OR (hoa hoi)). hieu ve cham duc van tuan cac chu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach kho tang ((((ha hoi) OR (xa hoi))) or (hoa hoi)). hieu ve cham duc van tuan cac chu tre~".
• Adding a wildcard symbol may retrieve word variants: te sach kho tang ((((ha hoi) OR (xa hoi))) or (hoa hoi)). hieu ve cham duc van tuan cac chu tre*.
