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