**elasticsearch官方默认的分词插件**

1、**elasticsearch官方默认的分词插件，对中文分词效果不理想。**

比如，我现在，拿个具体实例来展现下，**验证为什么，es官网提供的分词插件对中文分词而言，效果差**。

**总结**

如果直接使用Elasticsearch的朋友在处理中文内容的搜索时，肯**定会遇到很尴尬的问题——中文词语被分成了一个一个的汉字，当用Kibana作图的时候，按照term来分组，结果一个汉字被分成了一组。**

这是因为使用了Elasticsearch中默认的标准分词器，这个分词器在处理中文的时候会把中文单词切分成一个一个的汉字，因此**引入es之中文的分词器插件es-ik就能解决这个问题**。

**如何集成IK分词工具**

**　总的流程如下：**

第一步：**下载es的IK插件**https://github.com/medcl/elasticsearch-analysis-ik/tree/2.x

第二步：使用maven对**下载的es-ik源码进行编译**(mvn clean package -DskipTests)

第三步：把编译后的target/releases下的elasticsearch-analysis-ik-1.10.3.zip文件**拷贝到ES\_HOME/plugins/ik**目录下面，然后使用unzip命令解压

如果unzip命令不存在，则安装：yum install -y unzip

第四步：**重启es服务**

第五步：**测试分词效果**： curl 'http://your ip:9200/zhouls/\_analyze?analyzer=ik\_max\_word&pretty=true' -d '\{"text":"这里是好记性不如烂笔头感叹号的博客们"\}'

** 　　注意：若你是单节点的es集群的话，则只需在一台部署es-ik。若比如像我这里的话，是3台，则需在三台都部署es-ik，且配置要一样。**

**elasticsearch-analysis-ik-1.10.0.zip　　对应于　　elasticsearch-2.4.0**

**elasticsearch-analysis-ik-1.10.3.zip　　对应于　　elasticsearch-2.4.3**

**第一步**: 在浏览器里，输入[https://github.com/][https_github.com]

![855959-20170224212911163-403893892.png][]

**第二步**：[https://github.com/search?utf8=%E2%9C%93&q=elasticsearch-ik][https_github.com_search_utf8_E2_9C_93_q_elasticsearch-ik]

成功，得到。

这里，需要本地（即windows系统）里，提前安装好maven，需要来编译。若没安装的博友，请移步，见

# [Eclipse下Maven新建项目、自动打依赖jar包（包含普通项目和Web项目）][Eclipse_Maven_jar_Web] #

最后得到是，

**第八步**：**将最后编译好的，分别上传到3台机器里。$ES\_HOME/plugins/ik**目录下,注意需要新建ik目录。

其实，若想更具体地，看得，es安装中文分词器es-ik之后，的变化情况，直接，在$ES\_HOME下，执行bin/elasticsearch。当然，我这里只是给你展示下而已，还是用bin/elasticsearch -d在后台启动吧！

**第十二步**：测试，安装了es中文分词插件es-ik之后的对中文分词效果

**　　ik\_max\_word方式来分词测试**
