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