Hi,

need some help please!  
I expect that **A)** and **B)** leads to the same result.  
However, in A), using the \_analayze API leads to what I expect. In B), defining "my\_analyzer" like i do in A) in "mytest01" index do not lead to same result.  
Why is that so?  
(Im using ES 7.4.1 and Kibana 7.4.2)

**A)**

```
GET _analyze
{
  "char_filter": [
    {
      "type" : "mapping",
      "mappings" : [":) => _smile1_"]
    }
  ],
  "tokenizer": "standard",
  "text": "Hello World :)"
}

```

\*\*\* Returns

```
{
  "tokens" : [
    {
      "token" : "Hello",
      "start_offset" : 0,
      "end_offset" : 5,
      "type" : "<ALPHANUM>",
      "position" : 0
    },
    {
      "token" : "World",
      "start_offset" : 6,
      "end_offset" : 11,
      "type" : "<ALPHANUM>",
      "position" : 1
    },
    {
      "token" : "_smile1_",
      "start_offset" : 12,
      "end_offset" : 14,
      "type" : "<ALPHANUM>",
      "position" : 2
    }
  ]
}

```

**B)** Defined in an index

```
PUT mytest01
{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_analyzer" : {
          "type" : "custom",
          "character_filter" : "my_cfilter",
          "tokenizer" : "standard"
        }
      },
      "char_filter": {
        "my_cfilter": {
          "type" : "mapping",
          "mappings" : [":) => _smile_"]
        }
      }
    }
  }
}

POST mytest01/_analyze
{
  "analyzer": "my_analyzer",
  "text": "Hello World :)"
}

```

\*\*\* returns

```
{
  "tokens" : [
    {
      "token" : "Hello",
      "start_offset" : 0,
      "end_offset" : 5,
      "type" : "<ALPHANUM>",
      "position" : 0
    },
    {
      "token" : "World",
      "start_offset" : 6,
      "end_offset" : 11,
      "type" : "<ALPHANUM>",
      "position" : 1
    }
  ]
}

```

try `char_filter` instead of `character_filter` in the `my_analyzer` setup.
