Google表格选择，计数和限制

Question

在Google表格文档中，我有一列包含多个值。 我想按计数获取前20个值，然后对其他计数进行分组。

我现在有这个工作代码：

=QUERY(B2:B165,"select B, count(B) group by B order by count(B) desc limit 20 label B 'Pubblication venue'")

这将使我知道一个值出现在该列中的次数，并将结果限制为20。现在，我需要计数其他结果（〜100）。

让我通过示例进行解释。通过我的代码，我可以得到A，B和C的数量。现在我想要其他的数量。

+-------+----+
| A     | 5  |
+-------+----+
| B     | 2  |
+-------+----+
| C     | 4  |
+-------+----+
| Other | 90 |
+-------+----+

={QUERY(B2:B165, 
 "select B, count(B) 
  where B is not null
  group by B 
  order by count(B) desc 
  limit 20 
  label B 'Pubblication venue'", 0); 
 {"Other", COUNTA(IFERROR(QUERY(QUERY(B2:B165, 
 "select B, count(B) 
  where B is not null
  group by B 
  order by count(B) desc 
  offset 20
  label count(B)''", 0), 
  "select Col1", 0)))}}
