es-plugin

elasticsearch-hanlp

当前支持分词类型：

• hanlp / hanlp-standard: 标准分词
• hanlp-index: 索引分词

编译、安装、测试

文件路径按着自己的安装路径设置

1. 编译、打包插件

gradle -p es-plugin jar buildPluginZip

2. 使用命令安装插件

ES_HOME/bin/elasticsearch-plugin install file:///home/hldev/hldata/data/hanlp-ext/es-plugin/build/distributions/elasticsearch-hanlp-5.4.3.zip

3. 修改 ES_HOME/config 目录下的 jvm.options 文件添加一行（读取hanlp.properties配置文件需要）

-Djava.security.policy=file:///你的ES目录/plugins/elasticsearch-hanlp/plugin-security.policy

4. 最后修改ES/bin/elasticsearch.in.sh文件将 ES_CLASSPATH修改为

ES_CLASSPATH="$ES_HOME/lib/elasticsearch-5.4.3.jar:$ES_HOME/lib/*:$ES_HOME/plugins/elasticsearch-hanlp/"

最后运行elasticsearch即可

测试方法：

分别使用以下两种方式测试分词效果：

GET /_analyze?pretty
{
  "analyzer" : "hanlp",
  "text" : ["重庆华龙网海数科技有限公司"]
}

输出：
