全文检索技术_IK分词器7.7.1版本的安装

1. 在linux系统中，首先将将IK分词器下载下来

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

将文件加压到Elasticsear安装目录的plugin/analysis-ik下

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

2. 重启Elasticsearch服务

systemctl restart elsaticsearch.service

3. 验证IK分词器

curl -H 'Content-Type: application/json'  -XGET 'localhost:9200/_analyze?pretty' -d '{"analyzer":"ik_max_word","text":"赵利文的CSDN博客内容最近更新挺频繁"}'

结果：
