索引

创建索引

创建一个索引，包含2个分片1份副本(settings)，指定了2个字段类型(mappings) 。

PUT greeting
{
    "settings" : {
      "number_of_shards" : 2, 
      "number_of_replicas" : 1 
    },
    "mappings" : {
        "_doc" : {
            "properties" : {
                "email" : { "type" : "keyword" },
                "message" : { "type" : "text" }
            }
        }
    }
}

写入索引

POST book/_doc
{
  "email" : "[email protected]",
  "message" : "hello world"
}

写入索引（指定ID）

POST book/_doc/1
{
  "email" : "[email protected]",
  "message" : "hello world"
}

Bulk 批量写入

POST greeting/_bulk
{ "index" : { "_type" : "_doc"} }
{ "email" : "[email protected]","message":"hello1" }
{ "index" : { "_type" : "_doc"} }
{ "email" : "[email protected]","message":"hello2" }
{ "index" : { "_type" : "_doc"} }
{ "email" : "[email protected]","message":"hello3" }
{ "index" : { "_type" : "_doc"} }
{ "email" : "[email protected]","message":"hello4" }
