=== `_type`

Each document indexed is associated with an id and a type. The type,
when indexing, is automatically indexed into a `_type` field. By
default, the `_type` field is indexed (but *not* analyzed) and not
stored. This means that the `_type` field can be queried.

The `_type` field can be stored as well, for example:

[source,js]
--------------------------------------------------
{
    "tweet" : {
        "_type" : {"store" : true}
    }
}
--------------------------------------------------

The `_type` field can also not be indexed, and all the APIs will still
work except for specific queries (term queries / filters) or faceting
done on the `_type` field.

[source,js]
--------------------------------------------------
{
    "tweet" : {
        "_type" : {"index" : "no"}
    }
}
--------------------------------------------------
