=== UAX URL email tokenizer
++++
<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.

=== Example output

[source,console]
---------------------------
POST _analyze
{
  "tokenizer": "uax_url_email",
  "text": "Email me at john.smith@global-international.com"
}
---------------------------

{
  "tokens": [
    {
      "token": "Email",
      "start_offset": 0,
      "end_offset": 5,
      "type": "<ALPHANUM>",
      "position": 0
    },
    {
      "token": "me",
      "start_offset": 6,
      "end_offset": 8,
      "type": "<ALPHANUM>",
      "position": 1
    },
    {
      "token": "at",
      "start_offset": 9,
      "end_offset": 11,
      "type": "<ALPHANUM>",
      "position": 2
    },
    {
      "token": "john.smith@global-international.com",
      "start_offset": 12,
      "end_offset": 47,
      "type": "<EMAIL>",
      "position": 3
    }
  ]
}

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):

      }

[ john, smith, globa, l, inter, natio, nal.c, om ]
