# 自定義分析器
當內置分析器不能滿足您的需求時,您可以創建一個custom分析器,它使用以下相應的組合:
* 零個或多個[字符過濾器](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-custom-analyzer.html)
* 一個[?分析器](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-tokenizers.html)
* 零個或多個[token過濾器](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-custom-analyzer.html)。
## 配置
custom(自定義)分析器接受以下的參數:
?
|
`tokenizer`
|
內置或定制的標記器。 (需要)
|
|
`char_filter`
|
內置或自定義[字符過濾器](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-charfilters.html)的可選陣列。
|
|
`filter`
|
可選的內置或定制token過濾器陣列。
|
|
`position_increment_gap`
|
在索引文本值數組時,Elasticsearch會在一個值的最后一個值和下一個值的第一個項之間插入假的“間隙”,以確保短語查詢與不同數組元素的兩個術語不匹配。 默認為100.有關更多信息,請參閱[position_increment_gap](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/position-increment-gap.html)。
|
## 配置示例
以下是一個結合以下內容的示例:
字符過濾器
* [HTML Strip Character Filter](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-htmlstrip-charfilter.html "HTML Strip Char Filter")
分詞器
* [Standard Tokenizer](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-standard-tokenizer.html "Standard Tokenizer")
Token 分析器
* [Lowercase Token Filter](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-lowercase-tokenfilter.html "Lowercase Token Filter")
* [ASCII-Folding Token Filter](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-asciifolding-tokenfilter.html "ASCII Folding Token Filter")
|
`PUT my_index`
`{`
`"settings"``: {`
`"analysis"``: {`
`"analyzer"``: {`
`"my_custom_analyzer"``: {`
`"type"``:??????``"custom"``,`
`"tokenizer"``:?``"standard"``,`
`"char_filter"``: [`
`"html_strip"`
`],`
`"filter"``: [`
`"lowercase"``,`
`"asciifolding"`
`]`
`}`
`}`
`}`
`}`
`}`
`POST my_index/_analyze`
`{`
`"analyzer"``:?``"my_custom_analyzer"``,`
`"text"``:?``"Is this <b>déjà vu</b>?"`
`}`
|
上述句子將產生以下詞語:
?
|
`[ is,?``this``, deja, vu ]`
|
前面的例子使用了默認配置的tokenizer,令牌過濾器和字符過濾器,但是可以創建每個配置的版本并在自定義分析器中使用它們。
以下是一個比較復雜的例子:
字符過濾器
* [Mapping Character Filter](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-mapping-charfilter.html "Mapping Char Filter"),?
分詞器
* [Pattern Tokenizer](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-pattern-tokenizer.html "Pattern Tokenizer"),?配置為分割標點符號
Token 分析器
* [Lowercase Token Filter](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-lowercase-tokenfilter.html "Lowercase Token Filter")(小寫分析器)
* [Stop Token Filter](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-stop-tokenfilter.html "Stop Token Filter")(停止分析器),?配置為使用預定義的英文停止詞列表
## 示例
|
`PUT my_index`
`{`
`"settings"``: {`
`"analysis"``: {`
`"analyzer"``: {`
`"my_custom_analyzer"``: {`
`"type"``:?``"custom"``,`
`"char_filter"``: [`
`"emoticons"`
`],`
`"tokenizer"``:?``"punctuation"``,`
`"filter"``: [`
`"lowercase"``,`
`"english_stop"`
`]`
`}`
`},`
`"tokenizer"``: {`
`"punctuation"``: {`
`"type"``:?``"pattern"``,`
`"pattern"``:?``"[ .,!?]"`
`}`
`},`
`"char_filter"``: {`
`"emoticons"``: {`
`"type"``:?``"mapping"``,`
`"mappings"``: [`
`":) => _happy_"``,`
`":( => _sad_"`
`]`
`}`
`},`
`"filter"``: {`
`"english_stop"``: {`
`"type"``:?``"stop"``,`
`"stopwords"``:?``"_english_"`
`}`
`}`
`}`
`}`
`}`
`POST my_index/_analyze`
`{`
`"analyzer"``:?``"my_custom_analyzer"``,`
`"text"``:?????``"I'm a :) person, and you?"`
`}`
|
|
[](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/analysis-custom-analyzer.html#CO283-1)?
|
表情符號字符過濾器,標點符號化器和english_stop令牌過濾器是在相同索引設置中定義的自定義實現。
|
以上示例產生以下詞語:
|
`[ i'm, _happy_, person, you ]`
