number_of_shards 分片
number_of_replicas备份份数
PUT /lib/ #lib为索引，这里创建一个索引
{
"settings": {
"index":{
"number_of_shards":5,
"number_of_replicas": 1
}
}
}
运行结果：

获得所有信息
GET /_all/_settings
Multi-Get批量查询:
PUT /index/a/1
{
"name": "ZhangSan",
"age": 18
}
PUT /index/a/3
{
"name": "LiSi",
"age": 20
}
//使用mget通过索引类型和id获取相关信息
GET /_mget //这里获得了2个文档
{
"docs":[
{
"_index": "index",
"_type": "a",
"_id": "1"
},
{
"_index": "index",
"_type": "a",
"_id": "3"
}
]
}
获得指定的字段
第一个只获取name字段，第二个只获取name、age字段
GET /_mget
{
"docs":[
{
"_index": "index",
"_type": "a",
"_id": "1",
"_source":"name"
},
{
"_index": "index",
"_type": "a",
"_id": "3",
"_source":["name", "age"]
}
]
}
或者简化写法
GET /index/a/_mget
{
"docs":[
{
"_id": "1",
"_source":"name"
},
{
"_id": "3",
"_source":["name", "age"]
}
]
}
或者
GET /index/a/_mget
{
"ids":["1", "3"]
}
结果：
{
"docs" : [
{
"_index" : "index",
"_type" : "a",
"_id" : "1",
"_version" : 1,
"_seq_no" : 0,
"_primary_term" : 1,
"found" : true,
"_source" : {
"name" : "ZhangSan"
}
},
{
"_index" : "index",
"_type" : "a",
"_id" : "3",
"_version" : 1,
"_seq_no" : 0,
"_primary_term" : 1,
"found" : true,
"_source" : {
"name" : "LiSi",
"age" : 20
}
}
]
}
