# Letter tokenizer [analysis-letter-tokenizer]
|
|
|
|
|
|
The `letter` tokenizer breaks text into terms whenever it encounters a character which is not a letter. It does a reasonable job for most European languages, but does a terrible job for some Asian languages, where words are not separated by spaces.
|
|
|
|
|
|
## Example output [_example_output_11]
|
|
|
|
```console
|
|
POST _analyze
|
|
{
|
|
"tokenizer": "letter",
|
|
"text": "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone."
|
|
}
|
|
```
|
|
|
|
The above sentence would produce the following terms:
|
|
|
|
```text
|
|
[ The, QUICK, Brown, Foxes, jumped, over, the, lazy, dog, s, bone ]
|
|
```
|
|
|
|
|
|
## Configuration [_configuration_12]
|
|
|
|
The `letter` tokenizer is not configurable.
