The `whitespace` analyzer breaks text into terms whenever it encounters a
whitespace character.

The above sentence would produce the following terms:

[source,text]
---------------------------
[ The, 2, QUICK, Brown-Foxes, jumped, over, the, lazy, dog's, bone. ]

=== Configuration

The `whitespace` analyzer is not configurable.

[discrete]
=== Definition

It consists of:

Tokenizer::
* <<analysis-whitespace-tokenizer,Whitespace Tokenizer>>

If you need to customize the `whitespace` analyzer then you need to
recreate it as a `custom` analyzer and modify it, usually by adding
token filters. This would recreate the built-in `whitespace` analyzer
and you can use it as a starting point for further customization:

[source,console]
----------------------------------------------------
PUT /whitespace_example
{
  "settings": {
    "analysis": {
      "analyzer": {
        "rebuilt_whitespace": {
          "tokenizer": "whitespace",
          "filter": [         <1>
          ]
        }
      }
    }
  }
}
----------------------------------------------------
// TEST[s/\n$/\nstartyaml\n  - compare_analyzers: {index: whitespace_example, first: whitespace, second: rebuilt_whitespace}\nendyaml\n/]

<1> You'd add any token filters here.
