Hi,

I created a new index with the following settings:

```
{
    "settings": {

    "analysis": {

      "filter": {

        "persian_stop": {

          "type": "stop",

          "stopwords": "_persian_"

        }

      },

      "char_filter": {

        "zero_width_spaces": {

          "type": "mapping",

          "mappings": [

            "\\u200C=> "

          ]

        }

      },

      "analyzer": "persian",

      "persian": {

        "tokenizer": "standard"
		   }
	    }
    }
}

```

after inserting a document let's say of type "video".  
The analyzer setting is not applied to fields of this type thus the queries do not return the desired result.  
Do I need to define an analyzer for every type's fields or setting an analyzer in my index setting suffice?

Thank you in advance for your assistance  
N.
