I implement weakly-routing using elaticsearch processors.  
I need to generate the formy index yyyy-MM-W, i.e. for the date 05/19/2020, the index -2020-05-4 must be created.

I use the processor:

```auto
     "date_index_name" : {
          "field" : "add_time",
          "index_name_prefix" : "testtime-",
          "index_name_format":"yyyy-MM-W",
          "date_rounding" : "d",
          "date_formats":["yyyy-MM-dd HH:mm:ss.SSS"]
        }
    }

```

Test message:

```auto
PUT /testtime/_doc/10
{
    "add_time": "2020-05-19 01:41:42.303"
}

```

However, as a result, an index of type testtime-2020-05-1 is formed. For any date, the week value is 1.

As I understood from the documentation, the date format conforms to the java standard.  
Is this format not supported or am I doing something wrong?  
I understand that you can use a hack: round the date by week value and use the date format yyyy-MM-dd, in fact it will be the same, but the resulting index names do not quite correspond to reality.
