The "include_type_name" parameter was temporarily introduced in #37285 to facilitate moving the default parameter setting to "false" in many places in the documentation code snippets. Most of the places can simply be reverted without causing errors. In this change I looked for asciidoc files that contained the "include_type_name=true" addition when creating new indices but didn't look likey they made use of the "_doc" type for mappings. This is mostly the case e.g. in the analysis docs where index creating often only contains settings. I manually corrected the use of types in some places where the docs still used an explicit type name and not the dummy "_doc" type.

=== Whitespace Analyzer
|
|
|
|
The `whitespace` analyzer breaks text into terms whenever it encounters a
|
|
whitespace character.

|
|
[float]
|
|
=== Example output
|
|
|
|
[source,js]

|
|
"analyzer": "whitespace",

The above sentence would produce the following terms:
|
|
|
|
[source,text]
|
|
---------------------------
|
|
[ The, 2, QUICK, Brown-Foxes, jumped, over, the, lazy, dog's, bone. ]

[float]

|
=== Configuration
|
|
|
|
The `whitespace` analyzer is not configurable.
|
|
|
|
[float]
|
|
=== 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,js]
|
|
----------------------------------------------------
|
|
PUT /whitespace_example
|
|
{
|
|
"settings": {
|
|
"analysis": {
|
|
"analyzer": {
|
|
"rebuilt_whitespace": {
|
|
"tokenizer": "whitespace",
|
|
"filter": [ <1>
|
|
]
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}

// CONSOLE
|

// 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.
