ElasticSerach整合中文分词器elasticsearch-analysis-ik6

ElasticSerach整合中文分词器elasticsearch-analysis-ik6

注：接上两章的ElasticSerach安装以及kibana安装。

1、下载对应的中文分词器，上传到Linux中，解压到ElasticSerach的plugins中，重启ElasticSerach即可，ElasticSerach会自动识别分词器。

cd /opt/es/elasticsearch-6.3.1/plugins

2、若启动报一下错误。

不要慌，删除/opt/es/elasticsearch-6.3.1/logs下的elasticsearch.log，重新启动就OK了。
3、进行分词器的一个测试，
先put添加数据了，在测试，否则没有数据测试。记得添加中文数据。
Ik(中英文分词器)有两个：
1 ik_smart（简易分词）
2 ik_max_word（尽最大可能分词）
其他不会的语法自己去看文档，我懂的也不多。
