elasticsearch中配置ik中文分詞器（LINUX）

一、安裝ES

二、配置ik

1.下載下傳ik

[https://github.com/medcl/elasticsearch-analysis-ik/releases]

(注意：版本最好與es對應)

2.打包(如果是下載下傳zip，則跳過這一步)

使用maven對下載下傳的es-ik源碼(tar.gz)進行編譯

3.解壓

将壓縮包複制到es安裝目錄下的/plugins/ik目錄下面，然後使用unzip指令解壓

三、測試

1.重新開機es

2.測試 ip/索引/_analyze

{

“analyzer”:“ik_max_word”, //ik_max_word:最細粒度劃分；ik_smart:最少切分

“text”:“公安部：各地校車将享最高路權”

}

我是用的POSTMAN，在頁面也可以直接操作

測試結果如下：

{
    "tokens": [
        {
            "token": "公安部",
            "start_offset": 0,

        }
    ]
