<titleabbrev>UAX URL email</titleabbrev>
|

|
|
|
|
The `uax_url_email` tokenizer is like the <<analysis-standard-tokenizer,`standard` tokenizer>> except that it
|
|
recognises URLs and email addresses as single tokens.
|
|
|
|
[discrete]
|
|
=== Example output
|
|
|
|
[source,console]
|
|
---------------------------
|
|
POST _analyze
|
|
{
|
|
"tokenizer": "uax_url_email",

"text": "Email me at john.smith@global-international.com"

The above sentence would produce the following terms:
|
|
|
|
[source,text]
|
|
---------------------------
|
|
[ Email, me, at, john.smith@global-international.com ]
|
|
---------------------------
|
|
|
|
while the `standard` tokenizer would produce:
|
|
|
|
[source,text]
|
|
---------------------------
|
|
[ Email, me, at, john.smith, global, international.com ]

|
|
=== Configuration
|
|
|
|
The `uax_url_email` 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`.
|
|
|
|
[discrete]
|
|
=== Example configuration
|
|
|
|
In this example, we configure the `uax_url_email` tokenizer to have a
|
|
`max_token_length` of 5 (for demonstration purposes):
