Hi guys,  
I have a cluster running and I have run into a problem involving including special characters in my search query. Now I did not setup the mapping for the index the mapping is dynamic and the analyzer is also standard. The information about the analyzer I got from the "Analyze API".

```auto
>  
> GET /<index>/_analyze
> {
> "text": "some-data"
> }

```

gave me the output

```auto
{
  "tokens": [
    {
      "token": "some",
      "start_offset": 0,
      "end_offset": 4,
      "type": "<ALPHANUM>",
      "position": 0
    },
    {
      "token": "data",
      "start_offset": 5,
      "end_offset": 9,
      "type": "<ALPHANUM>",
      "position": 1
    }
  ]
}

```

my current mapping

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

```

Because of this output I came to the conclusion that the analyzer here is standard and the special character is not indexed. Now when I try to include special character in my search query I am not getting the desired results and when I am trying to use another analyzer in search query I am receiving null results.  
Now My question is do I have a way to include special character in my search query any other way other than changing my mapping.
