# UAX URL Email Tokenizer **uax_url_email tokenizer** 类似 **standard tokenizer**，只不过它会把 **URL** 和 **email **地址当成一个词元。 原文链接 : [https://www.elastic.co/guide/en/elasticsearch/reference/5.4/analysis-uaxurlemail-tokenizer.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/analysis-uaxurlemail-tokenizer.html) 译文链接 : [http://www.apache.wiki/pages/editpage.action?pageId=10028865](http://www.apache.wiki/pages/editpage.action?pageId=10028865) 贡献者 : [陈益雷](/display/~chenyilei)，[ApacheCN](/display/~apachecn)，[Apache中文网](/display/~apachechina) ## **输出示例** ``` POST _analyze { "tokenizer": "uax_url_email", "text": "Email me at john.smith@global-international.com" } ``` 上面的句子会生成如下的词元: ``` [ Email, me, at, john.smith@global-international.com ] ``` 而 `standard` tokenizer 会生成： ``` [ Email, me, at, john.smith, global, international.com ] ``` ## **配置**  **`uax_url_email` tokenizer** 接受以下参数： _**max_token_length**_   单个 token 的最大长度。如果一个 token 超过这个长度，则以  `max_token_length 为间隔分割。默认值是` `255`.。 ## **配置示例** 下面的例子中，我们配置标准分词器的  `max_token_length 为 5 (便于展示)：` ``` PUT my_index { "settings": { "analysis": { "analyzer": { "my_analyzer": { "tokenizer": "my_tokenizer" } }, "tokenizer": { "my_tokenizer": { "type": "uax_url_email", "max_token_length": 5 } } } } } POST my_index/_analyze { "analyzer": "my_analyzer", "text": "john.smith@global-international.com" } ``` 输出如下： ``` [ john, smith, globa, l, inter, natio, nal.c, om ] ```
