2.原因分析
   出现此种错误信息 analyzer [ik_smart] has not been configured in mappings，提示需要配置es 的分析插件：ik_smart.也就是需要安装ik到es的plugins目录

3.解决方法：

执行如下命令安装插件
 D:\elasticsearch-8.14.3\bin> .\elasticsearch-plugin.bat install https://get.infini.cloud/elasticsearch/analysis-ik/8.14.3

注意事项：

    1.安装的分析插件ik_smart版本必须与elasticsearch版本一致

    2.安装完成重启elasticsearch
