1. 安装插件
1.1 安装插件
拼音分词器：/medcl/elasticsearch-analysis-pinyin
中文分词器：/medcl/elasticsearch-analysis-ik
找到自己对应的自己的Elasticsearch版本的插件进行安装
Elasticsearch 7.5.1elasticsearch-analysis-ik 7.5.1elasticsearch-analysis-pinyin 7.5.1
直接进入Elasticsearch安装目录下，依次进行在线安装
./bin/elasticsearch-plugin install /medcl/elasticsearch-analysis-ik/releases/download/v7.5.1/elasticsearch-analysis-ik-7.5.1.zip./bin/elasticsearch-plugin install /medcl/elasticsearch-analysis-pinyin/releases/download/v7.5.1/elasticsearch-analysis-pinyin-7.5.1.zip
安装完成后需要重启 elasticsearch,然后测试分词器是否OK,正常情况下会出现一堆分词结果
1.2 测试中文分词器
POST http://data:9200/_analyze{"analyzer":"ik_smart","text":"新型冠状病毒"}
分词结果
{"tokens": [{"token": "新型","start_offset": 0,"end_offset": 2,"type": "CN_WORD","position": 0},{"token": "冠状病毒","start_offset": 2,"end_offset": 6,"type": "CN_WORD","position": 1}]}
1.3 测试拼音分词器
POST http://data:9200/_analyze{"analyzer":"pinyin","text":"新型冠状病毒"}
分词结果
{"tokens": [{"token": "xin","start_offset": 0,"end_offset": 0,"type": "word","position": 0},{"token": "xxgzbd","start_offset": 0,"end_offset": 0,"type": "word","position": 0},{"token": "xing","start_offset": 0,"end_offset": 0,"type": "word","position": 1},{"token": "guan","start_offset": 0,"end_offset": 0,"type": "word","position": 2},{"token": "zhuang","start_offset": 0,"end_offset": 0,"type": "word","position": 3},{"token": "bing","start_offset": 0,"end_offset": 0,"type": "word","position": 4},{"token": "du","start_offset": 0,"end_offset": 0,"type": "word","position": 5}]}
2. 修改解析器
修改分词器，以下所有操作均是对song 索引库进行的操作
2.1 关闭索引
首先关闭索引，否则会报错的
POST http://data:9200/song/_close{}
2.2 配置IK+拼音分词
然后自定义分词器,我这里使用的IK_SMART+拼音
PUT http://data:9200/song/_settings{"index": {"analysis": {"analyzer": {"ik_pinyin_analyzer": {"type": "custom","tokenizer": "ik_smart","filter": "pinyin_filter"}},"filter": {"pinyin_filter": {"type": "pinyin","keep_first_letter": false}}}}}
你也可以使用IK_MAX_WORD + 拼音分词
PUT http://data:9200/song/_settings{"index": {"analysis": {"analyzer": {"ik_pinyin_analyzer": {"type": "custom","tokenizer": "ik_max_word","filter": "pinyin_filter"}},"filter": {"pinyin_filter": {"type": "pinyin","keep_first_letter": false}}}}}
2.3 开启索引
POST http://data:9200/song/_open{}
