我这里，

 

 

 

　　　　再，创建一个zhouls2的索引库。

[hadoop@master elasticsearch-2.4.0]$ curl -XPUT 'http://master:9200/zhouls2/'{
    "acknowledged":true}[hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$

 

 

　　得到

 

 

 

 

 

 

 　　在新创建的索引库zhouls2里，添加一条数据进去。

[hadoop@master elasticsearch-2.4.0]$ curl -XPOST http://master:9200/zhouls2/user/1 -d '{"name" : "lucy" , "age" : 18}'  {
   "_index":"zhouls2","_type":"user","_id":"1","_version":1,"_shards":{
   "total":2,"successful":2,"failed":0},"created":true}[hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$

 　　得到

 

 

 

 

 

 

 　　如下，是我用mget命令，为大家演示，通过xmget命令来获取多个文档

[hadoop@master elasticsearch-2.4.0]$ curl -XGET http://master:9200/_mget?pretty -d '{"docs": [{"_index":"zhouls" ,"_type":"user" ,"_id":2 ,"_source":"name"} ,{"_index":"zhouls2" , "_type":"user" ,"_id":1}]}'{  "docs" : [ {    "_index" : "zhouls",    "_type" : "user",    "_id" : "2",    "_version" : 1,    "found" : true,    "_source" : {      "name" : "john"    }  }, {    "_index" : "zhouls2",    "_type" : "user",    "_id" : "1",    "_version" : 1,    "found" : true,    "_source" : {      "name" : "lucy",      "age" : 18    }  } ]}[hadoop@master elasticsearch-2.4.0]$

 

 

 

 

 

 

　　如果我们需要的文档在同一个_index或者同一个_type中，我们就可以在URL中指定一个默认的/_index或者_index/_type。

[hadoop@master elasticsearch-2.4.0]$ curl -XGET http://master:9200/zhouls/user/_mget?pretty -d '{"docs": [{"_id":1} ,{"_id":2}] }'{  "docs" : [ {    "_index" : "zhouls",    "_type" : "user",    "_id" : "1",    "_version" : 1,    "found" : true,    "_source" : {      "name" : "john",      "age" : 28    }  }, {    "_index" : "zhouls",    "_type" : "user",    "_id" : "2",    "_version" : 1,    "found" : true,    "_source" : {      "name" : "john",      "age" : 28    }  } ]}[hadoop@master elasticsearch-2.4.0]$

 

 

 

 

 

 

 

 

　　如果我们的文档拥有相同的_index以及_type，直接在请求中添加ids的数组即可

[hadoop@master elasticsearch-2.4.0]$ curl -XGET http://master:9200/zhouls/user/_mget?pretty -d '{"ids":["1" ,"2"]}'{  "docs" : [ {    "_index" : "zhouls",    "_type" : "user",    "_id" : "1",    "_version" : 1,    "found" : true,    "_source" : {      "name" : "john",      "age" : 28    }  }, {    "_index" : "zhouls",    "_type" : "user",    "_id" : "2",    "_version" : 1,    "found" : true,    "_source" : {      "name" : "john",      "age" : 28    }  } ]}[hadoop@master elasticsearch-2.4.0]$
