一、安装插件
拼音分词扩展elasticsearch-analysis-pinyin安装
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" } } } } }
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" } }
