　　刚学有点懵懵的....

之前安装了es的ik分词器，继续试试...

IK分词效果有两种,一种是ik_max_word（最大分词）和ik_smart（最小分词）
post http://127.0.0.1:9200/_analyze
请求参数
{
"analyzer":"ik_smart",
"text":"中国abc"

}
返回
{
    "tokens": [
        {
            "token": "中国abc",
            "start_offset": 0,
            "end_offset": 5,
            "type": "CN_WORD",
            "position": 0
        }
    ]
}


如果是最细力度划分：
请求
{
"analyzer":"ik_max_word",
"text":"中国abc"

}

返回：

{

    "tokens": [

        {

            "token": "中国",

            "start_offset": 0,

            "end_offset": 2,

            "type": "CN_WORD",

            "position": 0

        },

        {

            "token": "abc",

            "start_offset": 2,

            "end_offset": 5,

            "type": "ENGLISH",

            "position": 1

        }

    ]

}

　　如果有些词我们不想拆看怎么办，配置自己的分词配置：

打开ik/config/IKAnalyzer.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
	<comment>IK Analyzer 扩展配置</comment>
	<!--用户可以在这里配置自己的扩展字典 -->
	<entry key="ext_dict">player3.dic</entry>
	 <!--用户可以在这里配置自己的扩展停止词字典-->
	<entry key="ext_stopwords"></entry>
	<!--用户可以在这里配置远程扩展字典 -->
	<!-- <entry key="remote_ext_dict">words_location</entry> -->
	<!--用户可以在这里配置远程扩展停止词字典-->
	<!-- <entry key="remote_ext_stopwords">words_location</entry> -->
</properties>

　新建player3.dic文件，写入自己的分词配置

 重启es项目

加载自己的配置文件

{
"analyzer":"ik_smart",
"text":"我非常喜欢三号小玩家他的网民player3是我喜欢的类型"

}
