• If you are trying to use Boolean operators, they must be ALL CAPS: (("te sach qua quan ly") OR ((("te sach phap quan ly") OR ("te sach nha quan ly"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"te sach qua quan ly\") or (((\"te sach phap quan ly\") OR (\"te sach nha quan ly\"))))*".
• Removing quotes may allow a broader search: (( te sach qua quan ly ) or ((( te sach phap quan ly ) OR ( te sach nha quan ly ))))*.
