ES version: 6.3

```auto

    "settings": {

                    "token_chars": [
                        "letter",
                        "digit"
                    ]

                    "filter": [
                        "lowercase",
                        "trim",
                        "asciifolding"
                    ]
                }
            },
            "normalizer": {
                "icu_normalizer": {
                    "type": "custom",
                    "char_filter": [
                        
                    ],
                    "filter": [
                        "icu_normalizer",
                        "trim"
                    ]
                }
            }
        }
    }
}

```

old index:

```auto
{
    "name": {
        "type": "text",
        "fields": {
            "keyword": {
                "type": "keyword",
                "normalizer": "icu_normalizer"
            }
        },
        "analyzer": "standard"
    }
}

```

new index (add a new field under "name"):

```auto
{
    "name": {
        "type": "text",
        "fields": {
            "autocomplete": {
                "type": "text",
                "analyzer": "nGram_analyzer"
            },
            "keyword": {
                "type": "keyword",
                "normalizer": "icu_normalizer"
            }
        },
        "analyzer": "standard"
    }
}

```

when I reindexed data from old\_index to new\_index, same query on "name" field itself doesn't return same results, it means the data in new\_index are not analyzed correctly
