• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach tu hang dai hoi. hieu van cham soc ban thanh lap ((cuu tre) OR (((cua te) OR (cua tu))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach tu hang dai hoi. hieu van cham soc ban thanh lap ((cuu tre) or (((cua te) OR (cua tu))))~".
• Adding a wildcard symbol may retrieve word variants: thu sach tu hang dai hoi. hieu van cham soc ban thanh lap ((cuu tre) or (((cua te) OR (cua tu))))*.
