撸了今年阿里、头条和美团的面试，我有一个重要发现.......>>>

1.从github中下载IK分词器，一定要注意和ES的版本一致

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

2 .下载之后放到 ES 的 \plugins 目录下面去重启 ES 服务

测试：http://localhost:9200/blog1/_analyze

{
   "text":"中华人民共和国MN","tokenizer": "ik_max_word"
}

结果：

{
    "tokens": [
        {
            "token": "中华人民共和国",
            "start_offset": 0,
            "end_offset": 7,
            "type": "CN_WORD",
            "position": 0
        },
        {
            "token": "中华人民",
            "start_offset": 0,
            "end_offset": 4,
            "type": "CN_WORD",
            "position": 1
        },
        {
            "token": "中华",
            "start_offset": 0,
            "end_offset": 2,
            "type": "CN_WORD",
            "position": 2
        },
        {
