文档： https://github.com/medcl/elasticsearch-analysis-pinyin

二、新建索引添加拼音支持

<index> 替换为 实际 index
<type> 替换为 实际 type

PUT <index>
{
  "settings" : { "analysis" : { "analyzer" : { "pinyin_analyzer" : { "tokenizer" : "my_pinyin" } }, "tokenizer" : { "my_pinyin" : { "type" : "pinyin", "keep_first_letter":false, "keep_separate_first_letter" : false, "keep_full_pinyin" : true, "keep_original" : false, "limit_first_letter_length" : 16, "lowercase" : true } } } }, "mappings": { "<type>": { "properties": { "name": { "type": "text", "index": true, "fields":{ "pinyin":{ "type":"text", "analyzer":"pinyin_analyzer" } } }, "link": { "type": "keyword", "index": false }, "id": { "type": "long" }, "update_time": { "type": "date", "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis" } } }
  }
}

分词测试

GET <index>/_analyze
{
  "field": "name.pinyin",
  "text": "内蒙古"
}

返回
{
  "tokens": [ { "token": "nei", "start_offset": 0, "end_offset": 1, "type": "word", "position": 0 }, { "token": "meng", "start_offset": 1, "end_offset": 2, "type": "word", "position": 1 }, { "token": "gu", "start_offset": 2, "end_offset": 3, "type": "word", "position": 2 }
  ]
}

二、已有索引添加拼音支持

1、新建索引

PUT <index>
{
  "mappings": { "<type>": { "properties": { "name": { "type": "keyword", "index": true }, "link": { "type": "keyword", "index": false }, "id": { "type": "long" }, "update_time": { "type": "date", "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis" } } }
  }
}

20
  
21
  
22
  
23
  
24
 

2、设置拼音分词器

POST  <index>/_close

PUT <index>/_settings
{
  "index": { "analysis": { "analyzer": { "pinyin_analyzer": { "tokenizer": "my_pinyin" } }, "tokenizer": { "my_pinyin": { "type": "pinyin", "keep_first_letter": true, "keep_separate_first_letter": true, "keep_full_pinyin": true, "keep_original": false, "limit_first_letter_length": 16, "lowercase": true } } }
  }
}

POST  <index>/_open

3、修改mapping，添加拼音分词器

PUT <index>/<type>/_mapping
{
  "<type>": { "properties": { "name": { "type": "keyword", "index": true, "fields":{ "pinyin":{ "type":"text", "analyzer":"pinyin_analyzer" } } }, "link": { "type": "keyword", "index": false }, "id": { "type": "long" }, "update_time": { "type": "date", "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis" } }
  }
}


GET <index>/_mapping


# 将当前索引的数据重新替换一下当前索引
POST <index>/_update_by_query?conflicts=proceed

4、搜索测试

get <index>/_search
{
  "query_string": { "fields": [ "name", "name.pinyin" ], "query": "王苏川", "default_operator": "AND"
  }
}
