ES搜索引擎基本操作

一.创建索引库

　　执行：，索引库的名称为zhen

　　结果（我已经创建过了，重复执行会报错）：

　　

二.创建索引

　　1.添加索引

　　2.添加索引（动态添加新列）

　　3.添加指定id的索引【根据id可以直接修改一前的索引】

三.搜索

　　1.根据id搜索

　　

　　2.根据字段搜索【每一个_source对应一条索引】

　　3.多条件组合搜索

　　执行：curl -H "Content-Type: application/json" -XPUT 'http://192.168.245.133:9200/zhen/' -d'{"settings":{"number_of_replicas":2}}'修改副本数　

　　注意：不能在创建索引之后修改配置！
