全文檢索技術_IK分詞器7.7.1版本的安裝

1. 在linux系統中，首先將將IK分詞器下載下來

wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.7.1/elasticsearch-analysis-ik-7.7.1.zip

將文件加壓到Elasticsear安裝目錄的plugin/analysis-ik下

unzip elasticsearch-analysis-ik-7.7.1.zip -d /usr/share/elasticsearch/plugins/analysis-ik

2. 重啓Elasticsearch服務

systemctl restart elsaticsearch.service

3. 驗證IK分詞器

curl -H 'Content-Type: application/json'  -XGET 'localhost:9200/_analyze?pretty' -d '{"analyzer":"ik_max_word","text":"趙利文的CSDN博客內容最近更新挺頻繁"}'
