# Standard Tokenizer(标准分词器) **`standard` tokenizer(标准分词器)**提供基于语法的分词(基于Unicode文本分割算法,如 [Unicode标准附件29](http://unicode.org/reports/tr29/) 中所述),并且适用于大多数语言。 原文链接 : [https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-standard-tokenizer.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-standard-tokenizer.html) 译文链接 : [http://www.apache.wiki/pages/viewpage.action?pageId=9405453](http://www.apache.wiki/pages/viewpage.action?pageId=9405453) 贡献者 : [陈益雷](/display/~chenyilei),[ApacheCN](/display/~apachecn),[Apache中文网](/display/~apachechina) ## **输出示例** ``` POST _analyze { "tokenizer": "standard", "text": "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone." } ``` 上面的句子会生成如下的词元: ``` [ The, 2, QUICK, Brown, Foxes, jumped, over, the, lazy, dog's, bone ] ``` ## **配置** **`standard` tokenizer(标准分词器) ** 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": "standard", "max_token_length": 5 } } } } } POST my_index/_analyze { "analyzer": "my_analyzer", "text": "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone." } ``` 输出如下: ``` [ The, 2, QUICK, Brown, Foxes, jumpe, d, over, the, lazy, dog's, bone ] ```
