Hey guys,

I'm building my application with C#.

I want to build an field with text and keyword with ignore\_above = int.MaxValue.  
All of that I want to do with attribute mapping of my model class.

```
[ElasticsearchType(Name = "doc")]
   public class MessageDto
   {
      [Text(Name = "message")]
      [Keyword(IgnoreAbove = int.MaxValue)]
      public string Message { get; set; }
   }
```

I have tried multiple cases:

Number 1:

```
[Text(Name = "message")]
   [Keyword(IgnoreAbove = int.MaxValue)]
   public string Message { get; set; }
```

Number 2:

```
[Text(Name = "message"), Keyword(IgnoreAbove = int.MaxValue)]
   public string Message { get; set; }
```

Both got me the same exception: \>\>Multiple custom attributes of the same type found.\<\<

The normal case without any annotation:

```
public string Message { get; set; }
```

Gets:

```
"message" : {
  "type" : "text",
  "fields" : {
    "keyword" : {
      "type" : "keyword",
      "ignore_above" : 256
    }
  }
}
```

But I want:

```
"message" : {
  "type" : "text",
  "fields" : {
    "keyword" : {
      "type" : "keyword",
      "ignore_above" : 2147483647
    }
  }
}
```

Everyone an idea, how it works?  
Thank you for helping me.
