@@ -421,5 +421,6 @@ The `unnest` datasource uses the following syntax:
 * `dataSource.base`: Defines the datasource you want to unnest.
   * `dataSource.base.type`: The type of datasource you want to unnest, such as 
a table.
 * `dataSource.virtualColumn`: [Virtual column](virtual-columns.md) that 
references the nested values. The output name of this column is reused as the 
name of the column that contains unnested values. You can replace the source 
column with the unnested column by specifying the source column's name or a new 
column by specifying a different name. Outputting it to a new column can help 
you verify that you get the results that you expect but isn't required.
+* `unnestFilter`: A filter only on the output column. You can omit this or set 
it to null if there are no filters.

tutorial](../tutorials/tutorial-unnest-arrays.md).
