elasticsearch中配置ik中文分词器（LINUX）

一、安装ES

二、配置ik

1.下载ik

[https://github.com/medcl/elasticsearch-analysis-ik/releases]
(注意：版本最好与es对应)

2.打包(如果是下载zip，则跳过这一步)

使用maven对下载的es-ik源码(tar.gz)进行编译

3.解压

将压缩包复制到es安装目录下的/plugins/ik目录下面，然后使用unzip命令解压

三、测试

1.重启es
2.测试 ip/索引/_analyze
{
“analyzer”:“ik_max_word”, //ik_max_word:最细粒度划分；ik_smart:最少切分
“text”:“公安部：各地校车将享最高路权”
}
我是用的POSTMAN，在页面也可以直接操作

测试结果如下：

{
    "tokens": [
        {
            "token": "公安部",
            "start_offset": 0,
            "end_offset": 3,
            "type": "CN_WORD",
            "position": 0
        },

        }
    ]
}
