• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chinh) OR (cho chinh)) sach - ((anh dang) OR (tinh bang)) cua bang cuong tap toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chinh) OR (cho chinh)) sach - ((anh dang) or (tinh bang)) cua bang cuong tap toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chinh) OR (cho chinh)) sach - ((anh dang) or (tinh bang)) cua bang cuong tap toan cao*.
