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"
}
{
"tokens": [
{
"token": "我",
"start_offset": 0,
"end_offset": 1,
"type": "CN_CHAR",
"position": 0
},
{
"token": "非常",
"start_offset": 1,
"end_offset": 3,
"type": "CN_WORD",
"position": 1
},
{
"token": "喜欢",
"start_offset": 3,
"end_offset": 5,
"type": "CN_WORD",
"position": 2
},
{
"token": "三号小玩家",

"end_offset": 10,

},

},

}
