• If you are trying to use Boolean operators, they must be ALL CAPS: (((("tu sach phap luat ly") OR ("su sach phap luat ly"))) OR ((("thu sach pham luan le") OR ("thu sach phat xuat ly"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"tu sach phap luat ly\") OR (\"su sach phap luat ly\"))) or (((\"thu sach pham luan le\") or (\"thu sach phat xuat ly\"))))*".
