安装IK中文分词和拼音插件

./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.3.2/elasticsearch-analysis-ik-6.3.2.zip

./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-pinyin/releases/download/v6.3.2/elasticsearch-analysis-pinyin-6.3.2.zip

我的ES版本是6.3.2，具体安装插件版本看自己的ES版本。

可以验证插件是否安装成功：

POST /_analyze
{
		"analyzer":"pinyin",
		"text":"北京东"
}

POST /_analyze
{
		"analyzer":"ik_max_word",
		"text":"北京东"
}

结果如下
