Binary field type

A binary field type contains a binary value in Base64 encoding that is not searchable.

Example

Create a mapping with a binary field:

PUT testindex 
{
  "mappings" : {
    "properties" :  {
      "binary_value" : {
        "type" : "binary"
      }
    }
  }
}

Index a document with a binary value:

PUT testindex/_doc/1 
{
  "binary_value" : "bGlkaHQtd29rfx4="
}

Use = as a padding character. Embedded newline characters are not allowed.
