• If you are trying to use Boolean operators, they must be ALL CAPS: (((("thuoc sach hoc tay nguoi") OR ("thuoc sach toc tay nguoi"))) OR ("sao ban thuc gian nguoi"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"thuoc sach hoc tay nguoi\") OR (\"thuoc sach toc tay nguoi\"))) or (\"sao ban thuc gian nguoi\"))*".
