• Removing quotes may allow a broader search: (( te sach nha quan ly ) OR ((((( te sach tham luan ly ) OR ( toc sach phap luan xay ))) OR ( te sach phap luat xay ))))~.
• Adding a wildcard symbol may retrieve word variants: (("te sach nha quan ly") OR ((((("te sach tham luan ly") OR ("toc sach phap luan xay"))) OR ("te sach phap luat xay"))))*.
