【IK分词器安装】

安装IK分词器：

下载链接（如果es版本不同可以修改下版本号）：https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.1/elasticsearch-analysis-ik-7.12.1.zip
通常下载是比较慢的：有需要可以从本文章附件资源下载，下载完后放到windows系统插件映射目录下。

依次执行

以下有些目录路径和es安装设置时相关，具体看文章：https://blog.csdn.net/sinat_37828702/article/details/134239500

注：后来发现windows只需要在windows指定目录映射文件直接解压插件压缩包到ik文件夹就行了！

重启es

C:\Users\lxh>docker ps
