windows上ES安装ik分词器

1.首先得知道ik分词器的地址

GitHub：GitHub - medcl/elasticsearch-analysis-ik

若github访问较慢，可以访问以下网站

mirrors / medcl / elasticsearch-analysis-ik · GitCode

2.手动安装

打开git的命令行

git clone https://github.com/medcl/elasticsearch-analysis-ik
#git clone https://gitcode.net/mirrors/medcl/elasticsearch-analysis-ik
cd elasticsearch-analysis-ik
git checkout tags/{version}
mvn clean
mvn compile
mvn package

然后找到克隆下来的文件进入\target\releases目录中，将elasticsearch-analysis-ik-*.zip解压到ES的\plugins\ik目录下。

3.重启ES

若ES日志文件中报如下错误

则进入到\plugins\ik目录下，找到plugin-descriptor.properties文件，将文件中的elasticsearch.version=改为自己的ES版本号
