1. 对应置顶版本插件
sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.17.0/elasticsearch-analysis-ik-7.17.0.zip

sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install https://github.com/infinilabs/analysis-ik/releases/download/v7.17.18/elasticsearch-analysis-ik-7.17.18.zip

sudo /usr/share/elasticsearch/bin/elasticsearch-plugin list

sudo systemctl restart elasticsearch

# 分词
curl http://127.0.0.1:9200/_analyze --header 'Content-Type: application/json' --data '{"analyzer":"ik_max_word","text":"世界如此之大"}'

ik 带有两个分词器
ik_max_word ：会将文本做最细粒度的拆分；尽可能多的拆分出词语
ik_smart：会做最粗粒度的拆分；已被分出的词语将不会再次被其它词语占有


# 热词更新配置
sudo vim /etc/elasticsearch/analysis-ik/IKAnalyzer.cfg.xml
