• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (cua chu)) sach - ((hanh tang) OR (anh tang)) luan cung trong dan toan ban~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (cua chu)) sach - ((hanh tang) or (anh tang)) luan cung trong dan toan ban*.
