Having any attachment field in the index breaks lenient queries.

[ha107642]

How to reproduce:

1. DELETE localhost:9200/platina
2. PUT localhost:9200/platina
3. PUT localhost:9200/platina/test/_mapping

{
    "test" : {
        "properties" : {
            "date" : {
              "type": "date",
              "format": "dateOptionalTime" 
          }
        }
    }
}

1. POST localhost:9200/platina/test/_search

{
  "query": {
        "query_string":{
          "fields": [ "*" ],
          "query": "hej",
          "lenient": true
        }
  }
}

Zero results are returned, since no documents exist.

1. PUT localhost:9200/platina/documents/_mapping

{
    "documents": {
        "properties": {
            "file": {
              "type": "attachment"
            }
        }
    }
}

1. POST localhost:9200/platina/test/_search

{
  "query": {
        "query_string":{
          "fields": [ "*" ],
          "query": "hej",
          "lenient": true
        }
  }
}

Performing the search again yields:

Note that there are no documents in the index, and the attachment field is not of the same type as the searched type.

Maybe I'm missing some leniency setting for this plugin. I'm not entirely sure how I can resolve this, so I hope you can shed some light on it! :)

Sorry, this is probably not related to this plugin, but rather one of the fields that the plugin creates.
