错误原因是，没有安装分词器 IK

如何安装分词器 IK

访问 https://github.com/medcl/elasticsearch-analysis-ik
点击如下图标注出的地方，选择发行的版本
ik_smart not found,elasticsearch,java,搜索引擎
点进来后，可以按下图所示的地方搜索自己想要的版本号

注：此处的版本号最好与 elasticsearch 的版本号保持一致

ik_smart not found,elasticsearch,java,搜索引擎

本文就选用 v6.6.2 版本，选择点击进入后，选择 zip 包点击下载，如下图：
ik_smart not found,elasticsearch,java,搜索引擎
下载好后解压，然后上传至 elasticsearch 的 plugins 文件夹下，下图中的路径是本文的安装路径，请小伙伴对照自己 elasticsearch 的路径

最后使用 docker-compose up -d 命令，重新启动文章来源地址https://www.toymoban.com/news/detail-615853.html
