elasticsearch中文分词器的安装和体验

因为本人使用的elasticsearch的版本为5.2.1,相对应的中文分词器的下载地址为https://github.com/medcl/elasticsearch-analysis-ik/tree/v5.2.1.(请根据自己使用版本的不同进行下载)

安装其实挺简单,编译后解压缩到elasticsearch的安装目录,以下是我的安装目录.

unzip -d /usr/local/elasticsearch/plugins/ik/ elasticsearch-analysis-ik-5.2.1.zip

然后重启elasticsearch.

我们还是插入四条数据,检索全部如下
