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