     An index is a logical namespace which maps to one or more
     <<glossary-primary-shard,primary shards>> and can have zero or more
  
positive.code:   This allows you access to the original object directly from search
    results, rather than requiring a second step to retrieve the object
    from an ID.

    Note: the exact JSON string that you indexed will be returned to you,
    even if it contains invalid JSON. The contents of this field do not
    indicate anything about how the data in the object has been indexed.

  [[glossary-type]] type ::
  
    A type represents the _type_ of document, e.g. an `email`, a `user`, or a `tweet`.
    The search API can filter documents by type.
    An <<glossary-index,index>> can contain multiple types, and each type has a
    list of <<glossary-field,fields>> that can be specified for
    <<glossary-document,documents>> of that type.  Fields with the same
    name in different types in the same index must have the same <<glossary-mapping,mapping>>
    (which defines how each field in the document is indexed and made searchable).
