• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"tu sach phap quan ly\") or (\"hoc sach tham quan ly\"))) or (((\"thuat lap pham quang ly\") or (\"thuat san pham quang huy\"))))) or (((\"thu hoan pchat quang khue\") or (((\"thu hoc hat quan he\") OR (\"thu hoc chat quang he\"))))))*".
