|
|
|
|
[source,text]
|
|
---------------------------
|
|

=== Configuration
|
|
|
|
The `whitespace` tokenizer accepts the following parameters:
|
|
|
|
[horizontal]
|
|
`max_token_length`::
|
|
|
|
The maximum token length. If a token is seen that exceeds this length then
|
|
it is split at `max_token_length` intervals. Defaults to `255`.
