I try to use kuromoji user dictionary to make Elasticsearch can analazed japanese name which with  
Half-width space between family name & first name.  
Settings example looks like the below:

```auto
{
  "settings": {
    "analysis": {
      "tokenizer": {
        "kuromoji_user_dict": {
          "type": "kuromoji_tokenizer",
          "mode": "normal",
          "user_dictionary_rules": [
              "渡辺 健,渡辺 健,ワタナベ ヒカリ,カスタム名詞",
            ]
        }
      },
      "analyzer": {
        "my_ja_analyzer": {
          "type": "custom",
          "tokenizer": "kuromoji_user_dict",
            "char_filter": [
              "icu_normalizer"
            ]
        }
      }
    }
  }
}

```

But I fund it dosen't worked well.A part of name was not analazed .

```auto
{
  "analyzer": "my_ja_analyzer",
  "text": "渡辺 健"
}
{
    "tokens": [
        {
            "token": "渡辺",
            "start_offset": 0,
            "end_offset": 2,
            "type": "word",
            "position": 0
        },
        {
            "token": " ",
            "start_offset": 2,
            "end_offset": 3,
            "type": "word",
            "position": 1
        }
    ]
}

```

Can somebody tells me what's wrong with it?
