Hi,

I've been trying to set up roman numbers synonyms the following way:

```auto
PUT testing_index
{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_custome_analyzer": {
          "type": "custom",
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "roman_letters_synonyms"
          ]
        }
      },
      "filter": {
        "roman_letters_synonyms": {
          "type": "synonym_graph",
          "synonyms": [
            "5 => v"
          ]
        }
      }
    }
  }
}

POST testing_index/_doc
{
  "name": "Grand Theft Auto V"
}

GET testing_index/_search 
{
  "query": {
    "match_phrase": {
      "name": "5"
    }
  }
}

```

But the last queue doesn't return the expected result.  
What am I doing wrong here?

Have you set `my_custome_analyzer` as the analyzer of the "name" field? You would do that in your mappings. Please post them if you did and are still experiencing this problem, its easier to re-create things that way.

I see, I thought that by defying it there it would be set automaticly.  
I set it as the index default and it fixed the problem.  
Thank you
