Enter multiple documents to same the same index in elastic search

Question

I'm new to elasticsearch, what I want to achieve is to insert multiple documents, that is, values to the same id in the index. Is it possible? When I try it the documents are getting updated. Let me know if it's possible ,thanks.

Answer 1

You can use the bulk-API to store multiple documents at once, but you can not store different documents with the same ID. Maybe you can achieve what you need by using the versioning feature .

Answer 2

What you are describing sounds like the Array Datatype . Per the ES documentation, you can put an array of strings into one field like so:

PUT my_index/_doc/1
{
  "message": "some arrays in this document...",
  "tags":  [ "elasticsearch", "wow" ], 
  "lists": [ 
    {
      "name": "prog_list",
      "description": "programming list"
    },
    {
      "name": "cool_list",
      "description": "cool stuff list"
    }
  ]
}
