ELASTIC 搜索開發實戰
一、安裝插件
拼音分詞擴展elasticsearch-analysis-pinyin安裝
文檔： https://github.com/medcl/elasticsearch-analysis-pinyin
二、新建索引添加拼音支持
替換為 實際 index
替換為 實際 type
PUT { "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": { "": { "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" } } } } }

二、已有索引添加拼音支持
1、新建索引
PUT { "mappings": { "": { "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" } } } } }
