Question

是否可以在不指定文档ID的情况下执行批量索引？我希望Elasticsearch在索引时为我生成一个随机ID，但可以这样做吗？

Answer 1

是的，你可以！

测试0.90.0.Beta1：

$ cat requests 
{ "index" : { "_index" : "test", "_type" : "type1" } }
{ "field1" : "value1" }

$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests; echo
{"took":6,"items":[{"create":{"_index":"test","_type":"type1","_id":"IWqsRqyhRVq-F69OLIngTA","_version":1,"ok":true}}]}

Answer 2

以下是批量上传的另一个示例，但未指定_id。

`

curl -XPOST "http://localhost:9200/_bulk" -d'
    { "index" : { "_index" : "test", "_type" : "demo" } }
    { "title" : "Quick brown rabbits", "content" : "Brown rabbits are commonly seen" }
    { "index" : { "_index" : "test", "_type" : "demo" } }
    { "title" : "Keeping pets healthy", "content" : "My quick brown fox eats rabbits

我们可以在不指定Elasticsearch的文档ID的情况下执行批量索引吗？
