}6.IK分词器：中文分词器
6.1 什么是IK分词器
ElasticSearch 几种常用分词器如下：
| 分词器 | 分词方式 |
| StandardAnalyzer | 单字分词 |
| CJKAnalyzer | 二分法 |
| IKAnalyzer | 词库分词 |
分词∶即把一段中文或者别的划分成一个个的关键字，我们在搜索时候会把自己的信息进行分词，会把数据库中或者索引库中的数据进行分词，然后进行一个匹配操作，默认的中文分词是将每个字看成一个词，比如“我爱中国"会被分为"我""爱""中""国”，这显然是不符合要求的，所以我们需要安装中文分词器ik来解决这个问题。
IK提供了两个分词算法：ik_smart和ik_max_word，其中ik smart为最少切分，ik_max_word为最细粒度划分!
ik_max_word: 会将文本做最细粒度的拆分，比如会将"中华人民共和国国歌"拆分为"中华人民共和国,中华人民,中华,华人,人民共和国,人民,人,民,共和国,共和,和,国国,国歌"，会穷尽各种可能的组合；
ik_smart: 会做最粗粒度的拆分，比如会将"中华人民共和国国歌"拆分为"中华人民共和国,国歌"。
6.2 Ik分词器的下载安装
注意：IK分词器插件的版本要和ElasticSearch的版本一致
下载完后，解压安装包到 ElasticSearch 所在文件夹中的plugins目录中：
再启动ElasticSearch，查看IK分词器插件是否安装成功：
安装成功！
6.3 使用Kibana测试IK
1、启动Kibana
2、访问请求：http://localhost:5601/
3、选择开发工具Dev Tools，点击控制台
4、在控制台编写分词请求，进行测试
IK提供了两个分词算法：ik_smart和ik_max_word，其中ik smart为最少切分，ik_max_word为最细粒度划分!
测试 ik_smart 分词算法，最少切分：
测试 ik_max_word 分词算法，最细粒度划分：
分词请求：
GET _analyze
{
"analyzer": "ik_max_word",
"text": "我爱中国共产党"
}分词结果：
{
"tokens" : [
{
"token" : "我",
"start_offset" : 0,
"end_offset" : 1,
"type" : "CN_CHAR",
"position" : 0
},
{
"token" : "爱",
"start_offset" : 1,
"end_offset" : 2,
"type" : "CN_CHAR",
"position" : 1
},
{
"token" : "中国共产党",
"start_offset" : 2,
"end_offset" : 7,
"type" : "CN_WORD",
"position" : 2
},
{
"token" : "中国",
"start_offset" : 2,
"end_offset" : 4,
"type" : "CN_WORD",
"position" : 3
},
{
"token" : "国共",
"start_offset" : 3,
"end_offset" : 5,
"type" : "CN_WORD",
"position" : 4
},
{
"token" : "共产党",
"start_offset" : 4,
"end_offset" : 7,
"type" : "CN_WORD",
"position" : 5
},
{
"token" : "共产",
"start_offset" : 4,
"end_offset" : 6,
"type" : "CN_WORD",
"position" : 6
},
{
"token" : "党",
"start_offset" : 6,
"end_offset" : 7,
"type" : "CN_CHAR",
"position" : 7
}
]
}比较两个分词算法对同一句中文的分词结果，ik_max_word比ik_smart得到的中文词更多（从两者的英文名含义就可看出来），但这样也带来一个问题，使用ik_max_word会占用更多的存储空间。
6.4 扩展字典
我们用分词器对 “万里顾一程” 进行分词：先使用 ik_smart 分词算法
在使用 ik_max_word分词算法，进行细粒度的划分：
GET _analyze
{
"analyzer": "ik_max_word",
"text": "万里顾一程"
}分词结果：
{
"tokens" : [
{
"token" : "万里",
"start_offset" : 0,
"end_offset" : 2,
"type" : "CN_WORD",
"position" : 0
},
{
"token" : "万",
"start_offset" : 0,
"end_offset" : 1,
"type" : "TYPE_CNUM",
"position" : 1
},
{
"token" : "里",
"start_offset" : 1,
"end_offset" : 2,
"type" : "COUNT",
"position" : 2
},
{
"token" : "顾",
"start_offset" : 2,
"end_offset" : 3,
"type" : "CN_CHAR",
"position" : 3
},
{
"token" : "一程",
"start_offset" : 3,
"end_offset" : 5,
"type" : "CN_WORD",
"position" : 4
},
{
"token" : "一",
"start_offset" : 3,
"end_offset" : 4,
"type" : "TYPE_CNUM",
"position" : 5
},
{
"token" : "程",
"start_offset" : 4,
"end_offset" : 5,
"type" : "CN_CHAR",
"position" : 6
}
]
}
使用上面两种分词算法后，发现 “万里顾一程”被分成了“万里”、“顾”、“一程”，这是因为在IK自带的字典中没有“顾一程”这个词，如果想得到“顾一程”这个词，怎么办呢？
这就要配置自己的扩展字典了，就是在IK分词器字典中加入我们自定义的字典，在词典中加入想要的词。
在ik分词器文件的config目录中新建自定义的字典文件，以.dic为后缀，并在文件中加入“顾一程”：
然后打开 IKAnalyzer.cfg.xml 文件，把自定义的字典添加到IK的字典中：
重启ES和Kibana，再用分词器对 “万里顾一程” 进行分词：此时“顾一程”就是一个词了。
