Whitespace analyzer [analysis-whitespace-analyzer]

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

Example output [_example_output_6]

POST _analyze
{
  "analyzer": "whitespace",
  "text": "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone."
}

The above sentence would produce the following terms:

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

Configuration [_configuration_7]

The whitespace analyzer is not configurable.

Definition [_definition_6]

It consists of:

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:

PUT /whitespace_example
{
  "settings": {
    "analysis": {
      "analyzer": {
        "rebuilt_whitespace": {
          "tokenizer": "whitespace",
          "filter": [         <1>
          ]
        }
      }
    }
  }
}

1. You’d add any token filters here.
