# UAX URL Email Tokenizer **uax_url_email?tokenizer**?類似?**standard?tokenizer**，只不過它會把?**URL**?和?**email?**地址當成一個詞元。 原文鏈接 : [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) 譯文鏈接 : [http://www.apache.wiki/pages/editpage.action?pageId=10028865](http://www.apache.wiki/pages/editpage.action?pageId=10028865) 貢獻者 : [陳益雷](/display/~chenyilei)，[ApacheCN](/display/~apachecn)，[Apache中文網](/display/~apachechina) ## **輸出示例** ``` POST _analyze { "tokenizer": "uax_url_email", "text": "Email me at john.smith@global-international.com" } ``` 上面的句子會生成如下的詞元: ``` [ Email, me, at, john.smith@global-international.com ] ``` 而?`standard`?tokenizer 會生成： ``` [ Email, me, at, john.smith, global, international.com ] ``` ## **配置** ?**`uax_url_email`?tokenizer**?接受以下參數： _**max_token_length**_ ? 單個?token 的最大長度。如果一個 token 超過這個長度，則以??`max_token_length 為間隔分割。默認值是`?`255`.。 ## **配置示例** 下面的例子中，我們配置標準分詞器的??`max_token_length 為 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" } ``` 輸出如下： ``` [ john, smith, globa, l, inter, natio, nal.c, om ] ```
