• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty hang x hoi. hieu ve cam ((xuc ban) OR (cuc ban)) anh te ((cua tre) OR (cua triet))~.
• Adding a wildcard symbol may retrieve word variants: thu sach ty hang x hoi. hieu ve cam ((xuc ban) or (cuc ban)) anh te ((cua tre) or (cua triet))*.
