1 安裝elasticsearch-analysis-ik中文分詞器

Ik介紹：ik是一款中文的分詞插件，支持自定義詞庫。

1.1 下載ik分詞器

下載地址：https://github.com/medcl/elasticsearch-analysis-ik/releases

下載指定版本的分詞器（zip版本）

1.2 解壓ik分詞器

[es@bigdata1 plugins]$ cd /home/es/
[es@bigdata1 ~]$ ls

[es@bigdata1 ~]$ mv elasticsearch/* ./elasticsearch-6.2.2/plugins/ik/
[es@bigdata1 ~]$ vim ./elasticsearch-6.2.2/config/elasticsearch.yml

1.3 重新啟動(dòng)Elasticsearch服務(wù)

ps -ef | grep elasticsearch
然后kill掉相關(guān)的進(jìn)程。
然后按照18.8的方式啟動(dòng)elasticsearch進(jìn)程

1.4 然后執(zhí)行以下命令

GET _analyze 
{ 
 "analyzer":"ik_smart", 
 "text":"2018年5月全球編程語言排行榜" 
}

運(yùn)行結(jié)果是：

{
"tokens": [
    {
      "token": "2018年",
      "start_offset": 0,
      "end_offset": 5,
      "type": "TYPE_CQUAN",
      "position": 0
    },
    {
      "token": "5月",
      "start_offset": 5,
      "end_offset": 7,
      "type": "TYPE_CQUAN",
      "position": 1
    },
    {
      "token": "全球",
      "start_offset": 7,
      "end_offset": 9,
      "type": "CN_WORD",
      "position": 2
    },
    {
      "token": "編程",
      "start_offset": 9,
      "end_offset": 11,
      "type": "CN_WORD",
      "position": 3
    },
    {
      "token": "語言",
      "start_offset": 11,
      "end_offset": 13,
      "type": "CN_WORD",
      "position": 4
    },
    {
      "token": "排行榜",
      "start_offset": 13,
      "end_offset": 16,
      "type": "CN_WORD",
      "position": 5
    }
]
}
